Description:
=======
When starting emacs server with `emacs --daemon', and connecting to it with
`emacsclient -c', then closing the last `emacsclient -c' frame and trying to
open a new `emacsclient -c' frame, the `emacs --daemon'
process receive SYSSEGV.
Steps to reproduce:
============
0. Make sure no Emacs processes are running.
1. Run: emacs --daemon
It prints:
("emacs")
Starting Emacs daemon.
and the process starts normally.
2. Run: emacsclient -c
It prints: Waiting for Emacs...
and a new frame opens as expected.
3. Close the frame, started on strep 2.
Observe that the `/tmp/emacs${UID}/server' socket seem to be active.
`fuser' on it prints the `emacs --daemon' PID.
4. (optional) Open `gdb', `attach' to the `emacs --daemon' process, and
`continue' it.
5. Run: emacsclient -c
It prints: Waiting for Emacs...
but no new frame is opened.
gdb prints something like:
Program received signal SIGSEGV, Segmentation fault.
0x00007f989f211527 in kill () from /lib/libc.so.6
And the output of `fuser /tmp/emacs${UID}/server' confirms that the socket
is stale.
6. Run: `emacsclient -c' prints:
emacsclient: connect: Connection refused
emacsclient: No socket or alternate editor. Please use:
--socket-name
--server-file (or environment variable EMACS_SERVER_FILE)
--alternate-editor (or environment variable ALTERNATE_EDITOR)

I'm sorry that no one got back to you on this, but I can't reproduce it
on either Emacs 23.4 or the latest Emacs repository. I think this must
have been fixed in the meantime; please let us know if you still
experience the behavior.
