win32

Environment is VC++ 9 on various Win platforms (XP and later)

I'm writing an unhandled exception handler. I have a vague recollection from my kernel days that it was bad to catch an EXCEPTION_GUARD_PAGE, as this was generated to tell the OS to enlarge the stack.

My question is twofold:

Can such an exception occur in user space?
If so, is it safe to catch it?

I'm not especially interested in doing anything with it. I just want to know if I need to put special code in to not catch it (as I'm catching everything at the moment).
