This is a Cygwin build of (a rather old version of) GDB, whereas Emacs
is a native Windows program.  I would suggest to download the latest
GDB binary available from the MinGW site (at least 7.0), and try with
it.  It might show a more meaningful backtrace, even when Emacs is
stuck in a system call.

What happens if you run it under GDB to begin with -- does it also
hang when you type "run" at the GDB prompt?  If it does, perhaps step
through the `main' function and see where it hangs.
