The most probable cause is something in your program, such as a null
pointer access. Usually these are bugs which remain hidden
in win95 because it has a buggy dpmi virtual memory management :-)

In bare dos you are using another dpmi server (cwsdpmi ?) which
traps the invalid memory access and bombs.

You can have a lot of help looking at those funny numbers printed
when your program crashed. Have a look at faq 9.1 and 9.2 for
more information on this topic (file faq210b.zip).
