Subject: Crash/Hang when restoring via Mac "resume" [Mac/NS]
Date: Sun, 5 Jan 2014 17:21:58 -0500

If started manually from Finder (rather than automatically after
logging in), Emacs hangs (1).

Sometimes, after a successful reboot and resume of the application, it
hangs when quitting (2).

Usually, when restarting after a boot (with resume), Emacs hangs in
ns_term_init (3).  [Note that this is with a vanilla GNU Emacs --with-ns,
current HEAD, on OS X 10.9.]

The problem is easily reproducible, and I have countless crash reports
from users.  It does not occur with an Emacs 23-based build.

(2) and (3) are in a [autoreleasepool release].

If it is a retain/release issue, NSZombieEnabled=YES won't bring 
up anything during normal runs, and 
I haven't figured out how to do it during resume on 10.9 (without
forking Emacs from within itself, which makes the error go away).

Setting the NSWindow to "not restorable" does not help.
(  [win setRestorable: NO] ).

Any other suggestions on how to debug this?

here.

Can you confirm whether these crashes are still happening?

The report was from beginning of 2014.  I don’t recall seeing a lot of these crashes more recently, so let’s close the bug.
