23.0.60; set-face-attribute crashes Emacs

[Eric Hanchrow]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In the src directory, I typed

   $ gdb --args emacs -Q --eval "(set-face-attribute 'default nil :height 20)"

This crashes; "bt" shows this trace:
