I have an M1 MacBook Pro running macOS Ventura 13.3 (22E252). I recently
updated Octave from 7.3.0 to 8.1.0 via Homebrew. Now, whenever I press Ctrl-C
in the Command Window, Octave immediately crashes.

I start Octave with this command in Terminal:

octave --gui &


After the crash, I see this message in Terminal:

octave exited with signal 6
