Did you maybe use the -fomit-frame-pointer on the compilation
command line?  This could cause the program to only crash in
the DPMI mode which is used under Windows.
Another thing to try is to run it under a different DPMI server,
like QDPMI or CWSDPMI, and see what happens then.  This could
separate the Windows effect from the DPMI effect.
