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. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
