--- Begin Message --- Subject: 25.0.93; Crash on OS X when suspending main frame Date: Thu, 5 May 2016 23:25:06 +0200

Emacs crashes when using the suspend-frame command (bound
to C-z by default) on the main frame.  It works correctly when the frame
is minimized by clicking on the GUI button.

Recipe: Start emacs -Q; type C-z; Emacs crashes with:
Fatal error 11: Segmentation faultAbort trap: 6

Partial crash dump from OS X console follows.  Please let me know if I can
be of further assistance.

Thanks in advance and best regards,
ICB

Hi!

I got OK from John to commit this to the emacs-25 branch. See http://git.savannah.gnu.org/cgit/emacs.git/commit/?h=emacs-25&id=06cb28ff3f24a29fa140d8af747d10abeed44293 for details.

Everybody -- thanks!

Hi!

This is good news! I can't recreate the problem here, most likely because I'm still on 10.10. However, it works for Alan and Ivan, who originally reported the problem, has confirmed that the patch corrects the problem.

Unless anybody objects, I will push the patch to "emacs-25" in a day or two. John?

Thanks everybody!

Thank you so much! I applied your patch to 25.0.93 and tried it on OS X, both with and without NSTRACE_ENABLED. It does not count as a formal test, but I can confirm no crashes after minimizing/restoring about 20 times each. I did it because here Emacs crashed most of the time, but not always, and it seemed to depend on timings.

Best regards,
Ivan
