[Vm-dev] [Pharo-project] fast #becomeForward: crashes without PharoV10.sources

[Esteban Lorenzano]

Hi Eliot, 

I have a very reproducible case :)

just take latest pharo 2.0 image, edit #condenseSources to remove: 

	VirtualMachine isRunningCogit
		ifTrue: [ self error: 'Sources cannot be condensed in a Cog (JIT enabled) Virtual Machine. Try a Stack VM.' ].

(so it runs it in cog :)

and  execute 

Smalltalk condenseSources.

BOOM! :)

and printAllStacks show that it stopped in #becomeForward:
