Subject: 29.1; Segmentation fault when setting mode-line-format

From: Ulrich Mueller <[email-masked]>
Date: Thu, 27 Jul 2023 12:02:27 +0200

$ emacs -Q -nw

In the *scratch* buffer, enter:

   (setq mode-line-format '((:propertize ("" mode-line-mule-info) display)))
   C-j

This will result in a "Fatal error 11: Segmentation fault".

The problem was already present in Emacs 26.3 but not in Emacs 25.3.
I can reproduce it both in a TTY and in an X (Lucid) frame.
