Hi. We are having a crash in Fuel, which doesn't crash with the standard VM. To reproduce, take a Pharo 1.2 image and load the attached mcz. You will see that method: #materializeKeysAndValuesTo:with:size: has a "self halt" inside.
If you ran the test FLCreateClassSerializationTest >> testCreateWithMethod it will crash. If you remove the "self halt" from #materializeKeysAndValuesTo:with:size: it works...
I debuged it with GDB and I don't know why, I can ONLY see the last two instrunctions, which is a longAt: -8 I attach screenshot. A bt or a call printAllStacks() doesn't show me anything.
If I run from a console, the only thing I get is a: Segmentation fault Smalltalk stack dump: Bus error
I have no idea what can be happening. Thanks for any clue...
