That does seem to be a bug, I have a look at it.  However, Emacs 23.1.50
should run GDB using GDB/MI (gdb -i=mi) not annotations (gdb --annotate=3)
so you shouldn't see any pre-prompt and post-prompt output.  I don't know
if you've customized gud-gdb-command-name or if your're manually editing
in the mini-buffer but you need to start with something like:

Run gdb (like this): gdb -i=mi yourprog

and you shouldn't need to kill the debugger.  Note that to stop the inferior
(program being debugged) you use C-c C-c (comint-interrupt-subjob) which
is signals BREAK on the pulldown menu.
