But do we really go into the VM to understand whatâs going on? Alexandre

Hi,
On last Moose image, I debugged the VM and executed âException signalâ. I paused the VM and saw that 2 methods are looping together in gcc3x-cointerp.c: static sqInt findMethodWithPrimitiveFromContextUpToContext(sqInt primitive, sqInt senderContext, sqInt homeContext); static sqInt findMethodWithPrimitiveFromFPUpToContext(sqInt primitive, char *startFP, sqInt homeContext);
The image is looping only when the debugger is launch on Error (not by launching it by the script below).
Maybe someone on the Pharo mailing list knows what is happening?
Thanks in advance,
Cheers, Vincent

Hi Vincent,
You example will also kill the Pharo debugger :) The issue is that you pass 'Processor activeProcess' which gets terminated when you close the debugger. When you open the debugger you need to make sure the process on which it is opened is suspended and can get terminated with no problem.
A different way to redo the example would be:
context := Context sender: nil receiver: {1 . 2 . 2} method: (OrderedCollection>>#add:) arguments: #(10). process := Process forContext: context priority: Processor userInterruptPriority. GTGenericStackDebugger openOn: (DebugSession process: process context: context).
There is a basic test for opening the debugger in GTGenericStackDebuggerSmokeTest but more could help.
Cheers, Andrei

Indeed. Maybe some tests has to be added..
But for now, it seems that the debugger is crashing the image⦠Not just by launching it: GTGenericStackDebugger openOn: (DebugSession process: Processor activeProcess context: (Context sender: nil receiver: {1 . 2 . 2} method: (OrderedCollection>>#add: ) arguments: #(10)))
But when an exception is thrown, its seems that we fall into an infinite loop around the primitive 199. Maybe the context is not well set?

This is weird that such bug can be introduced and no alarm is raised

Yep I had this problem (falled back to previous version), I suspected debugger being the reason.
