bug#13828: 24.3.50; Emacs freezes when using the emacs server, and exiting from a child frame

[Dima Kogan]

I'm running a very recent dev build of emacs. I'm observing that emacs
goes into an infinite loop, eats up all available CPU cycles, and
becomes unresponsive if I do the following:

1. emacs -Q --daemon ( this starts the daemon, and goes back to the
   shell )
2. emacsclient -c -a '' ( connect a client )
3. C-x 5 2 ( make new child frame )
4. C-x C-c ( kill emacs )

When using the emacs server, C-x C-c kills the current emacs client,
leaving the server intact to allow more clients to connect later. This
apparently doesn't work right if done from a child frame first.

(This bug report unfortunately got no response at the time.)

I'm unable to reproduce this in Emacs 28.  Are you still seeing this issue?

Thanks for looking at this report. It is over 7 years old! I don't see
this anymore. It probably has been fixed long ago, so I'm closing the
report.
