The above isn't a cygwin problem.  It's a standard problem in your
program just like you'd see in linux.  The difference between linux and
cygwin is that cygwin, by default, produces a stack trace file rather
than a core dump file.

So, the bottom line is that your program has a bug.  You need to track
down what the bug is and fix it.  gdb will probably help you do that.  If
you don't have gdb installed and you are writing programs you really
should install it.
