Well, that’s just about the last thing I was expecting.

I guess that closing a fullscreen window now results in it being
resized. But is emacsframe already trashed by this point? That would
certainly cause a crash.

Can you please uncomment line 54 in nsterm.h to enable NSTRACE,
recompile, cause the crash and send the output to me?
