There's no way to debug this except if we can interrupt Emacs when
it's looping.  I don't know how to do that, since I don't use Cygwin.
Please ask on the Cygwin mailing list how to interrupt a Cygwin
program when it runs under GDB; perhaps you can use the `kill'
command, if you have its Cygwin port installed.

Another possibility is to run Emacs outside GDB, and when it starts
looping invoke GDB as "gdb -p PID", where PID is the Emacs process ID
number.  If that succeeds, it will stop Emacs, and you should then be
able to do a backtrace.

And please don't remove the mailing list from the CC header, I'd like
to keep this discussion on the list so that others could contribute
ideas.
