It looks like Emacs was trying to reap a wrong process. dead_child
says its PID is 3744, but record_child_status_change, up above it in
the call stack, thinks its PID was 5412:
> #4 0x0101f2c6 in record_child_status_change (pid=-1, w=256) at process.c:6344
> deleted_pid = 5412
> all_pids_are_fixnums = false
> xpid = 21648
> record_at_most_one_child = true
> tail = 91890086
If that GDB session is still active, can you show the entire list in
deleted_pid_list? The 'pp' command should be able to display it in a
human-readable format.
Did this problem happen again since the original report? If it does
happen from time to time, I might ask you to run Emacs under GDB with
a couple of breakpoints in strategic places, because usually when
dead_child's handle is NULL, it is too late: the evidence of the crime
is already forgotten.
Thanks.
