This seems different from what the subject line suggests... :-)

It is not much information you give... :-)

First of all: what are other differences between the two systems?
If 586 runs win95 and 386 doesn't (I would like to see one :-) then
it could be a problem within your program.
The DPMI server within win95 doesn't catch null pointer references (ie it
allows them without complaining) while cwsdpmi does and crashes in reply.

Anyway, after the crash you should see a traceback printed on the screen.
Post this here so that we can have a look at it.
If you compile your program with debugging symbols (IIRC the -g switch)
and then you can see the stack of function calls using the utility
"symify".

>Is the some type of setup that I am missing?

I am not sure if it is important at runtime, but does the autoexec.bat
contain a line looking like "set DJGPP=c:/djgpp/djgpp.env" ?
