follow-up: I had time to check again... The mournQueue is initialized.
The image works pretty well with following VM (i.e. I can run all tests for example):

When I run it with latest trunk VM (compiled by myself) I get random crashes. The crash happens at startup with assert version of squeak.stack.spur. The VM stack dump is consistent with what I get in simulator (see attached)
From here, I don't know how to debug further...

More exactly this happens from: ... processWeakSurvivor: fireFinalization queueMourner: in self deny: (self is: anEphemeronOrWeakArray onObjStack: mournQueue).
If mournQueue is not initialized, and that's expected, then the assert needs to read
self deny: (mournQueue ~= 0 and: [self is: anEphemeronOrWeakArrayonObjStack: mournQueue]).
Check where the mournQueue is initialized. I may have written the code so that there is no mournQueue (mournQueue = 0) until the new finalization mechanism is enabled. If so, the assert needs updating.
If I write the code so that there's always a mournQueue (mournQueue is initialized in or from initializeObjectMemory:) then the asset is correct and mournQueue got zapped by mistake.

Hi, this question is mainly for Eliot I guess...
I have regular failures with a 32 bits squeak.stack.spur The VM crashes in garbage collect when running all tests.
When i simulate, I've got an assert: failure in
Spur32BitMMLESimulator>>is: oop onObjStack: objStack | index nextPage | self assert: (self numSlotsOfAny: objStack) = ObjStackPageSlots.
0 = 4092 fails...
Does it mean the image got corrupted?
