Open Radar

 
I often code with two windows open, one for code, one for a shell. When I'm done editing a file, I press C-x C-c to quit Emacs. However, when I do this in Mac OS X, my computer crashes.

Steps to Reproduce:

open Terminal.app
$ emacs
C-x 2
C-x o
M-x shell
C-x o
C-x C-f <file>
(finish editing)
C-x C-s
C-x C-c
"Active processes exist; kill them and exit anyway? (yes or no)"
yes
(OS crashes here)

System:

$ specs emacs brew bash os hardware

Mitigation:

Until this is resolved, I have to remember to safely quit the shell process before quitting Emacs.

C-x b *shell*
exit
"Process shell finished"
C-x C-c
