Emacs 25rc1 unstable on macOS 10.12

[Marius Kjeldahl]

Regarding the recent crashes on OSX discussed on this list on July
18th, I can confirm that it happens a few times a day on my system as
well after installing rc1.

I've checked the git repo and see no commits related to fixing this
yet. This will most likely hit all Emacs 25 users on Macs real soon so
I'm hoping the suggested patch or an alternative gets committed soon.

Thanks,

Marius K.
