Since when bugs are solved by fishing? ;-)

Seriously, though: why don't you try the methodical way of debugging?
Did you try it and it failed?  If so, please describe how the usual
debugging failed, and you will get more efficient help.

But assuming you did NOT try the normal debugging way, here's what you
should do:

       1) Convert the stack dump printed when the program crashes to a
          human-readable description using `symify' (see section 9.2
          of the DJGPP FAQ list for details).

       2) Run the program under a debugger, put a breakpoint at the
          point where it crashes, and try to see what goes wrong here
          (SIGSEGV usually means a bad pointer, so look for these
          first).

If the above doesn't help, post more info (at least the symified crash
dump).
