I just had a crash in delete_window and thought I'd do something about it before/rather than filing a bug report.... From the trace below, it seems like Fdelq is called, followed by a process_pending_signals and some redisplay, which probably crashes because the window has been half-deleted.
Would it be sensible in this case to add some BLOCK_INPUT statements to delete_window, or maybe SET_FRAME_GARBAGED? (Sorry if this is a naive suggestion.)

IIUC it was about to delete a single-window frame

so the first question is whether there were other frames left at that
time.

The downside of BLOCK_INPUT is that it makes Emacs unresponsive in the
sense that you can't even see a garbled frame when something goes wrong.
But yes - some general advice on why, whether and how BLOCK_INPUT should
be used would be very welcome.

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).
