Yes, please post all of the crash message, it includes lost of
important information.  Section 12.3 of the DJGPP FAQ explains how to
get an idea about the reason(s) of your crash using that info.  I
suggest to read that section, it might even help you find the bug by
yourself.

In this case, it looks like your code blew up the stack, e.g. by
overwriting some automatic array.  But it's very hard to know for sure
without seeing the crash message.

Yes, you need to give a dimension.
