Subject: 26.1; Emacs crashes trying to display CROSS MARK
Date: Fri, 08 Jun 2018 10:24:28 -0500

From emacs -Q:

C-x 8 RET CROSS MARK RET

crashes Emacs every time. Emacs also crashes when trying to display
CROSS MARK anywhere (mu4e uses this when mu4e-use-fancy-chars is
non-nil).

Let me know what other information I can provide

Thanks,
Alex

My crystal ball says that 'XFT_DEBUG=16 emacs' will say something
about loading an emoji font just before it crashes. I think youʼre the
third this week.

Is it possible for you to try the latest version of the emacs-26
branch? This should be fixed there.

Regards

Robert

Very nice crystal ball. The problem does indeed seem to be fixed on
emacs-26. Do you happen to know what commit(s) fix the issue? I'd like
to ask my distro to backport those commits until 26.2 gets released.

These 3 should do it:

* acaebed014 - (HEAD -> emacs-26) ; * src/ftfont.c (ftfont_spec_pattern): Fix whitespace. <Eli Zaretskii>
* 97d61f878e - Port FC_COLOR change to older fontconfig <Paul Eggert>
* f21fa142ac - Ignore color fonts when using Xft <Robert Pluim>

Closing the bug report, thanks for testing.
