This is explained at some length in section 12.2 of the DJGPP FAQ list
(v2/faq211b.zip from the same place you get DJGPP).  In short, most
probably, you installed some handler for a real-mode service and
didn't unsinstall it when the program exited.

This mostly happens when you write beyond the end of memory allocated
by some previous call to malloc.  See section 12.2 about this, too.
