Subject: 25.3; Emacs crash when running emacsclient
Date: Sun, 24 Dec 2017 12:29:06 -0800

I ran "emacsclient -c" to get a new Emacs frame on a system running MATE
on Debian 9.  IIRC, a new frame appeared for a split second and then
disappeared.  (I'm afraid the crash happened a few days ago and I'm just
now getting to filing the bug report.)  I found a core file; gdb says
there was a segmentation fault.  This is the first and only time I've
seen such a crash.

I'll hold onto the core file for a couple weeks in case there is
additional information to extract from it.

I don't think I've seen this crash since I upgraded to Emacs 26.  I
certainly can't remember the last time I saw it, so I'm going to go
ahead and close this bug.
