Your program probably does something invalid, like dividing by zero.  
Section 12.2 of the DJGPP FAQ list explains how to debug such problems 
using the crash traceback as a starting point.

If the FAQ doesn't help you, you definitely need to post more info.  For 
starters, find out where exactly does the program crash (use the `symify' 
utility, like the FAQ explains, for that), and post the code near that 
place.

It is also a good idea to post the exact crash message, complete with 
registers' dump and stack traceback, when reporting crashes.  People who 
know how to read that info can find some crucial hints therein.
