 Customize face-font-family-alternatives could lead to emacs crash
Date: Wed, 02 Jul 2014 16:37:03 +0800

[Message part 1 (text/plain, inline)]
Run following command could crash emacs:

cat <<END > test.el
    (progn (custom-set-variables
      '(face-font-family-alternatives
        '(("Monospace" "courier" "fixed")
          ("courier" "CMU Typewriter Text" "fixed")
          ("Sans Serif" "helv" "helvetica" "arial" "fixed")
          ("helv" "helvetica" "arial" "fixed"))))
       (char-displayable-p 215))
END
emacs -Q --load test.el

The face-font-family-alternatives value is taken from the default value.

`bt full` and `xbacktrace` attached.

(I'm going through old bug reports that unfortunately have not received
any responses yet.)

I'm unable to reproduce this bug in Emacs 27.  Are you still seeing it?
