That's very likely. The real crash occurred in delete_frame (not delete_window
as indicated).

It's entirely possible that there were no other frames left, or that there were
only hidden frames left - I usually hide the last frame in lieu of deleting it.
(I just had another one in delete_frame (see below), where this was the last
visible frame, but can't trace the origins, presumably also because of
compile-time optimizations used in that case). This one came via
kill-buffer-hook.
Any suggestions regarding tests or other debug code to insert?

Yes, it would be good to see this written up somewhere (perhaps it already is).
