bug#22174: 24.4; emacs --daemon crashes when ssh is disconnected. I am using lucid x toolkit.

[Cody Addison]

Eli,

Sure. I'll give it a try tonight and send you the results. A few more details that may help:

1. The exit command hangs. I typically have to use Ctrl-C. This only happens if I've opened emacsclient with X forwarding. I suspect the server still has an open connection over ssh, but this isn't really an area I know much about.

2. I exit the emacs client with C-x C-c. Sometimes I just put the laptop to sleep without closing emacs or the terminal. Both have the same results.

3. This was working for a while. I don't believe anything has changed since it stopped working, but it's possible. Right now I can reproduce the crash every time.

Can you attach GDB to the daemon before the final step, and when it
crashes (or exits or aborts or whatever), produce a backtrace and post
it here?

One more thing to try is the latest emacs-25 branch, if you can build
it or get a hold of snapshot binaries somewhere.

Thanks.
