bug#26323: 25.1; Closing frames (in fullscreen) under Mac OS cause immediate crash

[Kevin Sjöberg]

Start Emacs (GUI) and fullscreen the current frame. Create a new frame
(C-x 5 2), followed by closing the frame (C-x 5 0). This cause Emacs to
crash immediately. This does only happen if both frames are in
fullscreen.

This is not reproducible if the frames in question are not in fullscreen.
