If ``DOS 7'' means Windows 95, then such problems almost invariably mean 
that there's a bug in your program which goes undetected under Windows 
95.  When you work on plain DOS, DJGPP programs use the CWSDPMI program 
as the DPMI host, and CWSDPMI is much less tolerant to bugs whereby you 
try to access null pointer or do other forbidden things.

You should try to debug your program on DOS, using the crash traceback as 
the beginning.

The code produced by the compiler doesn't depend on the DPMI server.
