Subject: 23.1.50; Quitting gdb leaves a process behind
Date: Mon, 14 Sep 2009 23:54:48 +0300

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Start emacs with -q option, start gdb to debug any program
(M-x gdb RET C-a gdb -i=mi ./some-program), quit immediately by typing
quit RET to gdb command line (and answer "yes" to the question
whether to kill the process associated to the buffer) and finally list
processes with M-x list-processes RET.

Expected result: no processes.
Actual result:

Proc	     Status   Buffer   Tty	   Command
----	     ------   ------   ---	   -------
gdb-inferior run      (Killed) /dev/pts/15 

If I start gdb again after this, I get a new gdb-inferior<1>
process which again is left running when I quit gdb.

I've also seen cases where "quit" command to gdb does absolutely
nothing.  In at least some sub-cases, if I then say M-x list-processes
RET, _then_ I get the question whether to kill the process associated to
the buffer and if I say "yes", the debugger quits and I get "Debugger
finished" in the gdb buffer.
