This is nice. I don’t know what’s going on. I guess it’s maybe related
to the colour list we generate and which caused us some problems with
the high sierra beta last year.

Try deleting ’~/Library/Colors/Emacs.clr’. It will be recreated the
next time you run Emacs.

Try the attached patch, please. It replaces the above three commits.
If nobody objects I’ll push it to emacs-26 in a few days.

I believe it fixes the crash, but it still fails to redraw the frame
correctly when the font is changed. I don’t have 10.14 yet (and
probably won’t before the end of the year) so I can’t test it directly
myself.
