Using stock Emacs 28.2 from https://emacsformacosx.com/:

1) $ /Applications/Emacs.app/Contents/MacOS/Emacs -Q

2) open a second frame by, e.g., C-X-5-2

3) make it fullscreen, e.g., by clicking the green title button

4) delete the fullscreened frame by, e.g., C-X-5-0

I don't know enough about ObjC or NS to isolate the issue in the ObjC source, but the following work-around works for me:

(defun frame-turn-off-fullscreen (theframe)
  (if (eq 'fullboth
	  (cdr (assq 'fullscreen
		     (frame-parameters theframe))))
      (set-frame-parameter theframe 'fullscreen nil)))

(if (boundp 'ns-use-native-fullscreen)
    (add-to-list 'delete-frame-functions 'frame-turn-off-fullscreen))

I haven't tried this with Emacs in gdb, but do have macOS-generated crash logs I can send along upon request.

Also, I'm running this on macOS 13 (Ventura), but this has happened to me since macOS 10.13 (High Sierra) with Emacs 27 (possibly even earlier).  Reporting it only now because the work-around above has worked for me and I forgot about it.

I want to make one correction: I did indeed experience
a similar issue with macos 10.13, but just now I was
unable to reproduce it on older machines running 10.15
or 11.7.  So this may well be due solely to upgrading
to Ventura, and I may have pulled the trigger too
early on the bug report.  I will try to rebuild Emacs
on Ventura and see if that resolves the issue.

This distribution is done by someone outside of the Emacs project.  I
therefore suggest that you first report the problem to that person.

In general, we don't expect any Emacs 28 releases, so it would be of
great help to us if you could try Emacs 29 (from the master branch of
the Emacs Git repository) and see if the problem still exists there.
That's assuming the person who prepares these binaries concludes that
the problem is in the upstream code, not related to the particular way
these binaries are built.

Thanks.

I can reproduce this in feature/pkg, which should equal master in this
area.

So you are saying the NS-specific code that is run when Emacs is idle
somehow references a frame that was deleted?

I interpret the backtrace as saying that it's handling an event
(AppKit`-[NSApplication(NSEvent)
_nextEventMatchingEventMask:untilDate:inMode:dequeue:]), and the GUI
frame has been deleted.

Don't know about the idle part.

Look down the backtrace: this stuff was invoked from read_key_sequence
inside the command loop.  delete-frame is nowhere on the callstack, so
I conclude that delete-frame already exited, and we are in the idle
loop.

I can reproduce this on GNUstep, so expect a fix soon (anywhere between
2 to 5 hours depending on when I can get home.)

Great!  Kevin, if it's fixed for you as well, then I'll close this bug.

Don't know if this is important, but I see, on master, this printed to
the terminal, which is new AFAICt

2022-10-29 14:14:51.438 emacs[66923:1591049] +[CATransaction
synchronize] called within transaction

Alas, I don't know how to trigger this reproducibly.

Unfortunately, I can't make sense of that Apple mumbo jumbo, sorry.
According to a web search, it occurs on iOS when two animations are run
by the toolkit at the same time (which is probably the same on Mac OS.)
I guess it's fine if it doesn't lead to crashes.

No more comments within 2 weeks, so I'm closing the bug.
