Backtrace follows. The emacs executable was built without debug info so
function names only. Hope it is useful as a data point.

Does xbacktrace not work in that build?

In any case, this looks very similar to bug#76847, which was fixed in
the revision after the one your Emacs was built from.

bug#76847 also involved key-chord-mode, I think.

Nope.

Okay, then I'll build Emacs (this time with debug info!)

Usually I keep the same Emacs session until something forces me to close
it, which sometimes means several weeks. At that point Emacs is rebuilt
against HEAD. For igc, I think there is value on seeing how Emacs
behaves on that type of usage.

Feel free to close this bug report and, as always, thank you.

I don't know what's the best strategy here.  Maybe Eli has some advice.

> Feel free to close this bug report and, as always, thank you.

Closing, because it's probably that other bug.  Thanks for the report,
and please keep reporting issues no matter how you test!

There are no magic wands I know of.  One idea I can suggest is to
rebuild and restart a session whenever significant changes are
installed on the branch, especially if they are fixes of crashes
relevant to your platform.  Since the branch receives relatively few
changes lately, this would still allow you to run the same session for
prolonged times, something that indeed is useful and helpful.
