Oh...I just did:
Interpreter>>primitiveSetOSErrorCode | value | self export: true. value := self stackIntegerValue: 0. successFlag ifTrue:[ osErrorCode := value. self pop: argumentCount. ].
where
osErrorCode is an instvar in Interpreter...
(I found the variable declarations in interp.c, including gcBiasToGrowGCLimit like you pointed out, but I don't see how it ended up there!)

How about pasting your smalltalk code for primitiveSetOSErrorCode

I miraculously managed to somehow load VMMaker in Pharo on Windows XP.
Furthermore, I managed to create a new Primitive:
Interpreter>>primitiveSetOSErrorCode.
I was even able to use that primitive without the VM crashing!
But I can't seem to find the declaration of my instance variable
osErrorCode outside the scope of the primitive so I can use it in ioExit...
Any tips? Is there something special you have to do to create the
instance variables?
Thanks again for pointing me in the right direction...
