Subject: 27.0.91; crash
Date: Tue, 2 Jun 2020 17:28:18 -0600

Seems unlikely to recur but on the off chance this is helpful:
MacOSX 10.11.6 Emacs 27.0.91 crashed upon
      1	rapidly flipping between frames
      2	killing all but one frame
      3	switching input sources in the Apple menu bar
unclear whether it crashed after the second or third event.

(I'm going through old bug reports that unfortunately got no response at
the time.)

Have you seen this crash again in more recent versions of Emacs?

I've added Alan to the CCs; perhaps he has some insight here.

It's possible that commit f14869cd70e61b1908ec88a5e3d4bf21c7d538a0 has
fixed this, but I've not been able to reproduce most of these recent
crashes, so I can't say for sure.
