This comes from CWSDPMI, see section 12.2 of the FAQ.  That's why you 
don't see a traceback.

As I said earlier, I'd first suspect some stack smashage, like a huge 
automatic variable or extremely deep recursion.

You misunderstand what happens: the exception (GPF) indeed happens inside 
CWSDPMI, but the reason is outside CWSDPMI.  So CWSDPMI bugs are not 
relevant here; _your_ bugs are.
