GUD hangs when quitting GDBPlease describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

When I run GDB (M-x gdb, etc.) the first time, all goes well, until I
type "quit" in the GUD buffer, which never actually quits GDB (the
subprocess never dies).  I am able to quit GDB (and cause the message
"Debugger finished" to appear in the GUD buffer) by M-x list-processes.
The second time I run GDB, tab-completion (hitting tab in the GUD
buffer) hangs Emacs (C-g unfreezes).

The same happens when running `emacs -Q'.

I am running the development release of Emacs on Debian squeeze.

Regards,
Aidan Gauland
