You're trying to use a Cygwin GDB to cross-debug a MinGW (== plain old
win32) application. Dunno if that's completely guaranteed to work, but it
probably should for simple programs.

Assumption probably wrong.

Clue here. You are launching a win32 app, from a cygwin app, in a
(non-console-based) GUI window. Won't work. Use a console. See discussions
around CYGWIN=tty for full details (which, if you had it set, ought to make
the crash occur in a console as well as in rxvt/mintty, but isn't anything you
can turn off for rxvt and get it working).
