There are a few other possibilities. Check for any differences between your 
Debug and Release compiler and linker settings. Frequently, optimization is 
turned off during debugging to keep the instruction pointer from going all 
over the place as one is tracing through the code in the debugger, and it is 
turned back on to get smaller, faster code. As we all know, optimization bugs 
(and coding problems revealed by optimization) are not unheard of.

Another possibility is a different, smaller stack size for the Release link. 
The GPF you are seeing could be a result of stack overflow. By the way, what 
is the exact GPF you are seeing? There are several different kinds, and it 
might help pinpoint the problem...
