 Emacs daemon crashes on Mac OS X when closing fullscreen client frame
 with C-x C-c
Date: Sun, 1 Nov 2015 10:11:58 +0100

I am on a mac, using the MacPorts build of Emacs.app. When I connect to
an emacs daemon with emacsclient -c and switch to fullscreen mode,
everything works fine, until I exit the frame with C-x C-c: this crashes
the daemon.

Steps to reproduce the issue:

1. start the emacs daemon:
   $ open -a Emacs --args --daemon
2. open a client frame
   $ emacsclient -c
3. switch client frame to fullsreen mode (press the green maximize
   button in frame border)
4. exit the client frame with C-x C-c

This crashes the daemon, and the OS reports 'Emacs quit
unexpectedly'. Note that I do not have any problems with C-x C-c when
the client frame is not in fullscreen mode.

Regards,
Martijn

Hi, sorry it's taken so long for sopmeone to get back to you. I can't
reproduce this in Emacs 25. Could you possibly try the pretest and see
if it's still crashing?

Thanks. I'll close this bug report now, and if you find it recurring
in Emacs 25 later, please raise a new report.

I know that this issue is five years old but I have tried to unarchive it. I have the same issue with Emacs 27.2. Closing a fullscreen frame via 'C-x 5 0' or killing emacs from a full-screen frame via ‚C-x C-c‘ causes Emacs to crash on macOS 11.2.3.
