You didn't post enough information to identify the cause of your
problem.  My first guess would be that BIG[] is declared a local
array and is therefore overrunning the stack.  The DJGPP FAQ list
(v2/faq210b.zip from the same place you get DJGPP) explains this
problem and workarounds in section 15.9.

If the advice in the FAQ doesn't help, post here the shortest program
that reproduces the problem.
