FreeBSD bebop.silverbrook.com.au 4.2-STABLE FreeBSD 4.2-STABLE #0: Wed Nov 22 08:52:41 EST 2000     toor@bebop.silverbrook.com.au:/usr/obj/usr/src/sys/bebop  i386

>Description:
If gdb is attached to a process and that process subsequently exits
prior to gdb detaching then gdb fails to detach, issues an error
message and won't exit.  You have to kill gdb to quit.

Here's a sample of gdb's output at such a time,
(gdb) Quit
(gdb) The program is running.  Quit anyway (and detach it)? (y or n) y
Detaching from program: /home/andy/tmp/tstp, process 25834, thread 1
ptrace: No such process.
(gdb)

>How-To-Repeat:
Attach to process in gdb. Have process exit. Then try to quit gdb.

>Fix:
Seems likely to be a simple test of errno at the appropriate point.
