DEBT 2026: Call for Papers ================================================================================ DEBT 2026, Workshop co-located with ECOOP 2026, Brussels, Belgium Fourth Workshop on Future Debugging Techniques (https://2026.ecoop.org/home/debt-2026#Call-for-Papers) ================================================================================ Important Dates ----------------------- * Abstract submission deadline: Sat 28 Feb 2026 * Paper submission deadline: Sat 7 Mar 2026 * Author notification: Wed 15 Apr 2026 * Workshop: Monday 29 June 2026 ================================================================================ DEBTâ26 is looking to advance state-of-the-art to debug modern software. We welcome researchers from all related areas aimed at helping with the hard task of diagnosing the root cause of bugs, including dynamic and static debugging techniques, online and postmortem debuggers, delta debugging, automatic bug finding, novel visualization techniques for debugging programs, etc. The workshop aims to gather the community and foster discussion from different perspectives. That is why we seek submissions in the form of papers as well as talks and tool demonstrations. The workshop is a venue for all approaches to debugging. A non-exclusive list of topics of interest is: * Debugging techniques, from static to dynamic techniques. * Innovative visualisation techniques. * Techniques targeted specific programming models and execution models (e.g., concurrent and parallel programming, microservices, distributed ledgers, web, etc. ) or hardware (e.g., debugging micro-controllers, mobile devices, Big Data applications, etc.). * Case studies and evaluation of such techniques, e.g., user studies on visualisation tools, debuggers, etc. * Surveys, taxonomies of bugs and bug patterns, and current practices/uses of debugging approaches. Papers must be formatted according to the guidelines for ACM sigplanpapers (\documentclass[sigplan,screen]{acmart}), seehttps://www.sigplan.org/Resources/Author/ <https://www.sigplan.org/Resources/Author/>for details. Submissions should be made via Easychair using the following link:https://easychair.org/conferences/?conf=debt2026 <https://easychair.org/conferences/?conf=debt2026> The accepted papers will be published in the ACM Digital Library, though authors will be able to opt out of this publication, if desired. At least one author of an accepted paper must register for the workshop and attend the event to present the work, and participate in the discussions. AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of your conference. The official publication date affects the deadline for any patent filings related to published work. Workshop Organizers --------------------------- * Burcu Kulahcioglu Ozkan, Delft University of Technology, Netherlands * Steven Costiou, Centre Inria de lâUniversitÃ© de Lille, France For more information see: https://2026.ecoop.org/home/debt-2026

Fw: Pharo CIG Crash Issue
by MORGAN LEE GUAN HAN Dec. 5, 2025

Dec. 5, 2025

Forwarding the original email. ________________________________ From: MORGAN LEE GUAN HAN <1211107272(a)student.mmu.edu.my> Sent: Saturday, November 29, 2025 12:08 AM To: Aik-Siong Koh <askoh(a)askoh.com> Subject: Pharo CIG Crash Issue Dear Pharo Team, I am currently attempting to replicate what Esteban Lorenzano did for this Youtube Video<https://www.youtube.com/watch?v=U9fpvZJaFx4> (Esteban Lorenzano - Pharo-CIG: C++ Interface Generator - 23 April 2025), which is to generate C Bindings for Pharo uFFI to call, in Windows 11. Unfortunately, I am unable to replicate the results of the video. The results of my attempts leads to Pharo's Virtual Machine crashing and exiting abruptly to the launcher. I am unable to find any logs for this, and would appreciate your support for this matter. OS: Windows 11 Clang: https://github.com/llvm/llvm-project/releases/tag/llvmorg-18.1.8 (LLVM-18.1.8-win64.exe) Pharo Template: Pharo 14.0 - 64bit (development version, latest) Pharo CIG Github: https://github.com/pharo-cig/pharo-cig Raylib: https://github.com/raysan5/raylib Steps to Reproduce Step 1: Create Image [cid:1a4a23bb-52e6-47a5-b0a7-b251d6ddc8ea] Step 2: Installing Pharo CIG Open Playground wtih 'Ctrl + O + P' (or 'Cmd + O + P'). Copy and paste the Installation Code from the Pharo CIG Github<https://github.com/pharo-cig/pharo-cig>. Click the "Do it All" green triangle button on the top left of the Playground Window. [cid:2a667f99-b808-4950-a40a-798054e502e4] Step 3: Installing Clang Download and run the Pre-built binaries from this Github page<https://github.com/llvm/llvm-project/releases/tag/llvmorg-18.1.8> according to your platform. The folder named LLVM should be in your "C:\Program Files" directory after installation for Windows 11. Other installation methods may be used according to your preference. Step 4: Installing raylib Download or clone the raylib Github repository<https://github.com/raysan5/raylib>. Extract the folder ('raylib-master') if you are downloading the repository. Place the folder in a directory of your preference. E.g "C:\Users\morgan\raylib-master" Step 5: Setting Pharo CIG Requirements CIG needs to be able to find the clang library. If it cannot find it automatically, set the location in LibClang>>unix64LibraryName, e.g. - Pharo CIG Github<https://github.com/pharo-cig/pharo-cig> Open System Browser with 'Ctrl + O + B' (or 'Cmd + O + B'). Create a "win32LibraryName" method in the LibClang class under the CIG-LibClang package to set your "libclang.dll" location. This method is missing from the default installation. Paste in this code (There may be whitespace character issues): win32LibraryName ^ FFIWindowsLibraryFinder new userPaths: #('C:\Program Files\LLVM\bin'); findAnyLibrary: #('libclang.dll') [cid:3241b208-b515-4b7b-98fc-45312ec65c82] Save and create the method with 'Ctrl + S' (or 'Cmd + S'). [cid:7d0e72f0-4086-411a-8e27-c2b11c4df817] Step 6: The Example Recipe from Github Open Playground wtih 'Ctrl + O + P' (or 'Cmd + O + P'). Copy and paste the example recipe from Github <https://github.com/pharo-cig/pharo-cig?tab=readme-ov-file> into the Playground. Configure the example recipe from Github<https://github.com/pharo-cig/pharo-cig?tab=readme-ov-file>. Change "import:" and "cIncludedPath:" directories according to your file structure. E.g '/home/esteban/dev/vm/raylib/src/raylib.h' â 'C:\Users\morgan\raylib-master\src\raylib.h' Click the "Do it All" green triangle button on the top left of the Playground Window. This should cause the Virtual Machine to abruptly exit or crash. Code Snippet (There may be whitespace character issues): (lib := CigCLibraryGenerator new) "Prefix to be added to the generated classes (structures, enums, etc.)" prefix: 'Ray'; "name of the generated package (by default, is the same as the libraryName, capitalized)" packageName: 'Raylib'; "Library name. If not unixLibraryName, macLibraryName and winLibraryName are specified, it will be taken as base name for the existing libraries (e.g. in this case raylib.so, raylib.dylib and raylib.dll)" libraryName: 'raylib'; "headers to import (there can be as many of them as is needed)." import: 'C:\Users\morgan\raylib-master\src\raylib.h'; import: 'C:\Users\morgan\raylib-master\src\rcamera.h'; "include path (-I of c compiler), to allow libclang to find other included headers." cIncludePath: 'C:\Users\morgan\raylib-master\src'; "Since this is a graphical library, instruct the library to run in mainthread (otherwise, default is 'same thread' which is the same thread the pharo is running)" useMainThread. "generate the library" lib generate. [cid:55b4605c-3b19-45f0-8ed8-ef9093b6fa89] End of email.

MPLR 2026 Call for Papers
by stephane ducasse Nov. 13, 2025

Nov. 13, 2025

Dear Smalltalk friends Please find the following conference call for papers that can interest you. If you know other forums that could be interested in virtual machines, compilers â¦. do not hesitate to forward this call. S. Ducasse and C. Scholliers PC chair of MPLR 26 ################################################################################## The 23rd International Conference on Managed Programming Languages & Runtimes (MPLR, formerly ManLang, originally PPPJ) is a premier forum for presenting and discussing novel results in all aspects of managed programming languages and runtime systems, which serve as building blocks for some of the most important computing systems in use, ranging from small-scale (embedded and real-time systems) to large-scale (cloud-computing and big-data platforms) and anything in between (desktop, mobile, IoT, and wearable applications). https://2026.ecoop.org/home/mplr-2026 Important Dates --------------- - Abstract Submission Deadline: February 27, 2026 - Paper Submission Deadline: March 6, 2026 - Paper Author Notification: April 15, 2026 - Camera Ready for Papers: April 30, 2026 - Conference Date: June 29, 2026 All deadlines are 23:59 AoE (UTC-12h). #### Topics The areas of interest related to managed programming languages and runtime systems include but are not limited to: - **Virtual Machines** - Portable intermediate representations (e.g., JVM, WebAssembly, RPython, ...) - Managed runtime systems (e.g., GraalVM, Android Runtime (ART), V8, JavaScriptCore, .NET, â¦) - VM design and optimization - VMs for mobile and embedded devices - VMs for real-time applications - Memory management and garbage collection - Hardware/software co-design - Domain-specific languages - Security and privacy - Persistence - **Languages and Compilers** - Managed languages - Compilers and interpreters - Type systems and program logics - Language interoperability - Parallelism, distribution, and concurrency - **Techniques, Tools, and Applications** - Static and dynamic program analysis - Testing and debugging - Simulation - Refactorings - Program synthesis - Performance analysis and monitoring - Compiler and program verification and model checking If you are unsure whether a particular topic falls within the scope of MPLR â26 or if you have any other questions, please do not hesitate to contact the Program Chair. #### Submission Categories MPLR accepts three types of submissions: - **Regular research papers**, describing novel contributions involving managed language platforms. Research papers will be evaluated based on their relevance, novelty, technical rigor, and contribution to the state-of-the-art. (Format: up to 12 pages, excluding bibliography and appendix); - **Work-in-progress research papers**, describing hot topics or promising new ideas, with perhaps less maturity than full papers. Work-in-progress papers will be evaluated with an emphasis on novelty and the potential of the new ideas instead of technical rigor and experimental results. (Format: up to 6 pages, excluding bibliography and appendix); - **Industry and tool papers**, presenting technical challenges and solutions for managed language platforms in the context of deployed applications and systems. Industry and tool papers will be evaluated on their relevance, usefulness, and results. Suitability for demonstration and availability will also be considered for tool papers. (Format: up to 6 pages, excluding bibliography and appendix; up to 12 pages allowed if justified by the content); Accepted submissions will be published in the ACM Digital Library, except if the authors prefer not to be included. MPLR 2026 submissions must conform to the ACM Policy on Prior Publication and Simultaneous Submissions and to the SIGPLAN Republication Policy. See http://www.sigplan.org/Resources/Policies/Republication #### Author Instructions Submissions need to use the ACM SIGPLAN format with the `sigplan` style. If you are using LaTeX, submissions need to use the `acmart` document class with the `sigplan` option (*not* the `sigconf` option). In the `acmart-primary.zip` file that downloads from the LaTeX (Version 1.90) link on the https://www.acm.org/publications/proceedings-template page, look for `samples/sample-sigplan.tex` as a guide. If you use Overleaf, be sure to change the `documentclass` option `manuscript` to `sigplan`. For ease of reviewing, please include page numbers in your submission using the LaTeX command `\settopmatter{printfolios=true}`. Please use the standard setting, e.g., the default font size for the SIGPLAN style is 10 point and the format uses two columns for the test. All submissions need to be in PDF format. MPLR now uses **double-blind reviewing**. **Authors should not show their names on a submission and should refer to their own work in third person.** We further recommend that they avoid publicizing the work, at least under the same or similar title, while it is under review. Please also ensure that your submission is legible when printed on a black and white printer. In particular, please check that colors remain distinct and font sizes are legible. Submission Site: https://mplr26.hotcrp.com
