Subject: bug#62009: 29.0.60; Emacs crashes on setf symbol-name
Date: Mon, 06 Mar 2023 20:26:32 +0100	[thread overview]
Message-ID: <87o7p5of4n.fsf@daniel-mendler.de> (raw)

Execute the following in the scratch buffer:

(setf (aref (symbol-name 'car) 1) ?o)

Emacs crashes with a segmentation fault. Is this a well-known issue? I
could reproduce the problem on Emacs 27 and 29. Should there be some
mechanism to protect the strings of symbols?

I found the snippet on reddit:
