I have the VM compiled with debug support and gdb working. I can reproduce the crash. After checking a bit in the VM about what Eliot says, I found out methods like #clearLeakMapAndMapAccessibleObjects and #checkCodeIntegrity:. However, I tried, for example (clearLeakMapAndMapAccessibleObjects to later call checkCodeIntegrity(0) ) from gdb: ------ *fwdBlockValid(fwdBlock2) 40450* *Program received signal SIGSEGV, Segmentation fault.* *0x000ab6d2 in ??

Re: [Pharo-dev] vm crash in SmalltalkImage>garbageCollect

Hi Eliot, Is an assert vm the same as a vm compiled with debugging support? Also can you point me to any documentation about the leak checker.

Re: [Pharo-dev] problem using curl and wget in zero-conf -- explained

by Dale Henrichs

As I mentioned in the previous email, I sometimes have users report that they get the following error in their log file when installing pharo/GsDevKit-Home: > /home/travis/build/GsDevKit/GsDevKit_home/shared/pharo/pharo: line 11: > /home/travis/build/GsDevKit/GsDevKit_home/shared/pharo and I assumed that it was some sort of unreported error while downloading the pharo-vm (--silent used without --show-error for curl) ... fortunately I just started reliably getting this error on travis[1] and was able to track down the root cause of the bogus "file does not exist message" to the fact that the 32 bit libraries have not been installed[2]. It's true that the zero-conf script reports info that the 32-bit libraries were not installed, but the linux error message in this case is completely misleading ... it wasn't until I verified that the file did indeed exist[1] that I was able to investigate this further --- in my case I was expecting the 32-bit libraries to get installed in a later step and changes to the script structure resulted in the 32 bit library install being skipped ... At the end of the day, I think that error messages should not be suppressed by the zero-conf scripts, especially given the fact that the error message you get when a download does fail is pretty much the same as you'd get when you don't have the 32 bit libraries installed ... In my case, now that I understand that I cannot rely on a proper error error when 32-libraries have not been installed, I will have to see if I can come up with a way to provide a better error message for GsDevKit_home users ....

The leak checker will allow you to narrow down the cause. If the leak checker shows no corruption then its definitely a GC bug. If there leak checker does show corruption before GC then one still has to find out what caused the heap corruption, but you can use the leak checker to narrow the search.

In case more info is needed, you can look at an example of a failure on travis[1], where an apparently successful download of the vm ends up with a non-existent pharo/pharo-vm/pharo executable on linx ... I suspect (hope?) that I'm missing some crucial error information from the download...

I would also like the option of seeing the progress of the download of the sources AND vm, because sometimes I want to know how the download is going on, speed, etc. Regards! -- Esteban
