Subject: 30.0.50; crash in adjust_frame_glyphs (called by delete_frame)
Date: Mon, 10 Jun 2024 15:58:33 +0000

This is a continuation of bug 71224 and it may be a similar issue.
I'm using Emacs without X support but running it in an X terminal.
With glyph debug enabled. emacsclient, with -Q.

I was using the same reproduction procedure as in bug 71224. So I was
randomly mixing these 4 actions:
- call to (debug) to open a backtrace window
- call to (recurse) to cause an error
- open a new frame
- close a frame

In the beginning I was using this for-loop to cause more stress by
opening lots of frames, but I think it's not needed; the crash also
happened when I just had 2 manually opened frames.
for j in `seq 100`; do for i in `seq 10`; do urxvt -e emacsclient
'-nw' '-e' '(dired "~")' &; done; sleep 7 && killall emacsclient; done

Apparently we're in a case in which the frame's glyph matrix exists
but it has 0 rows, and adjust_frame_glyphs doesn't like that.

Backtraces+variables follow.

We are in the process of deleting this frame because its terminal is
being deleted.  So requiring that its glyph matrix has non-zero number
of rows makes no sense.  I installed a fix for that (hopefully, since
you didn't really present a recipe I could follow).

Thanks.

I can't also reproduce this a formula, but the solution seems fine and the
bug can be closed; thanks.
