File to reproduce the problem:
$ cat reproduce-crash.el
(set-fontset-font t '(#x10000 . #x1FFFF) '("Noto Color Emoji" . "unicode-bmp") nil 'append) (i
nsert "🥰")
(Also attached to this mail).
Then the crash can be reproduced like this:
$ emacs -q --file reproduce-crash.el --eval '(eval-buffer)'
X protocol error: BadLength (poly request too large or internal Xlib length error) on protocol
request 138
When compiled with GTK, Emacs cannot recover from X disconnects.
This is a GTK bug: https://gitlab.gnome.org/GNOME/gtk/issues/221
For details, see etc/PROBLEMS.
Fatal error 6: Aborted
It happens with Emacs 26.3 and also whith Emacs compiled from current
git master.
A similar problem happens when trying to show that font with "xfd"
$ xfd -fa "Noto Color Emoji"
Warning: Missing charsets in String to FontSet conversion
X Error of failed request: BadLength (poly request too large or internal Xlib length error)
Major opcode of failed request: 138 (RENDER)
Minor opcode of failed request: 20 (RenderAddGlyphs)
Serial number of failed request: 208
Current serial number in output stream: 271
This color emoji font contains bitmaps of emoji.

Fixed by adding "Noto Color Emoji" to face-ignored-fonts
instead. Closing.
Committed as eae50e88ef
but although I have commit eae50e88ef it still crashes for me.

I made a mistake, I compiled from git master but then used an older
installation for testing.
It *does* work with git master.
As can be seen in the attached screenshot, Emacs can display colour
emoji in the buffer. The screenshot uses the “Joypixels” font (Version
5.5), but it works with “Noto Color Emoji” as well. I just tested wrong.
Some sequences like
👩🦰 U+1F469 U+200D U+1F9B0 woman: red hair
🧑🦰 U+1F9D1 U+200D U+1F9B0 person: red hair
don’t render correctly in the screenshot, although they work
using the same (“Joypixels”) font in gedit. But that is a different
problem …
So I think this bug here can be closed.

You had me worried there for a moment :-)

Is this with a cairo build or an XFT one? Gedit will almost certainly
be using cairo. (Iʼd test it myself, but downloading joypixels
requires signing up, and Iʼm feeling ornery today).

Done with this message.

With a cairo build, I think with an XFT build it could not display these
color emoji fonts at all.

Joypixels is not needed, the problem can also be seen with Noto Color
Emoji.
I reported a new bug for the emoji sequence display problem here:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=39799
In gedit, both “Noto Color Emoji” *and* “Joypixels” can display most
emoji sequences correctly. The latest version of “Joypixels” seems to be
slightly more up-to-date and can display a few sequences correctly which
cannot yet be displayed correctly using the latest “Noto Color Emoji”
(build from current git master) but this affects only a handful of
sequences.
Most sequences display correctly in gedit and I think none of the emoji
sequences displays correctly in Emacs.
