I've been experiencing a crash since upgrading to Emacs 26.1 and MacOS 10.13.4. It happens when running server-start
(which is in my .emacs
file), and a stale server auth file exists from a previous Emacs instance.
Reproducing it is easy:
- Start Emacs 26.1.
- Customive variable
server-use-tcp
; set value to t and save for future sessions. - Run server-start.
- Copy the file
server
in the{server-auth-dir}
folder toserver-2
. - Quit Emacs.
- Rename
server-2
file toserver
. - Relaunch Emacs.
- Run server-start.
- Observe crash.
The crash log that I see is:
