--- Comment #34 from Corinna Vinschen <corinna at vinschen dot de> ---
We're encountering a reliable hang on Cygwin GDB 7.8 as well, and Cygwin's
GDB was never built with guile. It can simply be reproduced like this:
$ gdb /usr/bin/emacs-w32
[...]
(gdb) r
Starting program: /bin/emacs-w32.exe
[New Thread 3944.0xfe4]
[New Thread 3944.0xcb8]
[New Thread 3944.0xcdc]
[New Thread 3944.0xf0]
[New Thread 3944.0x9d4]
[New Thread 3944.0x9fc]
At this point the GUI program is up and running, for about a second.
Then the cursor stops moving and neither the inferior nor GDB can be
interrupted. A hard kill of GDB is required.
The previous Cygwin GDB version was 7.6.50, and it doesn't have this
problem.
