Try reading section 12.2 of the DJGPP FAQ list, it explains how to
approach such problems.

That's easy: just run your program under a debugger.  When the GPF
strikes, the debugger will kick in and you can examine the variables
as you see fit.

Of course, there's a possibility the bug won't happen under a
debugger, in which case it's probably some uninitialized memory that
gives you this trouble.
