Subject: 31.0.50; Loading "elisa.el" crashes Emacs
Date: Thu, 26 Jun 2025 15:55:35 +0200

Hello,

the recipe for this crash I get is quite simple:

I install the package "elisa" from Gnu Elpa.  Then, any action loading
the file "elisa", like simply

  M-: (require 'elisa) RET

instantly crashes Emacs.  In the terminal I'm left with this output:
