When I compile this program with the net release of gcc and debug it with
the net release of gdb, it gets a SIGSEGV and stops.

I click on "View" and "Stack" and the output is perfectly understandable.
I haven't tried specifically with Cygwin 1.1.8 so maybe there is some kind
of inexplicable problem with that version of Cygwin.  If that is the case
then the Cygwin snapshots may work better for people.
