bug#28661: 25.3; closing fullscreen frame on macOS 10.13 High Sierra causes crash

[Kevin Lin]

Dear Emacs maintainers,

Without any init files, I

1. start up Emacs from the Finder

2. open a second frame

3. make either frame fullscreen (by clicking on the
   green button in the title bar or running
   TOGGLE-FRAME-FULLSCREEN)

4. close the frame, either by clicking the red button
   or running DELETE-FRAME

On my machine, this causes Emacs to crash.

My copy of Emacs is the latest release from
https://emacsformacosx.com.  I have also tried this on
the latest nightly ("GNU Emacs 26.0.50 (build 1,
x86_64-apple-darwin13.4.0, NS appkit-1265.21 Version
10.9.5 (Build 13F1911)) of 2017-06-11") from that
site.  The behavior appears to be identical.

I just upgraded to macOS 10.13.  This did not happen
in 10.12.  I do not really view this behavior as a bug
in Emacs, per se, and more as a problem in High
Sierra, but am hoping a work-around can be found in
Emacs more quickly than getting Apple to fix this.

Thanks!
