bug#38788: 27.0.50; Emacs crashes with Google Noto Emoji Color Fonts installed

[Francis Meetze]

To reproduce install the Google Noto Emoji Color font library.

dnf install google-noto-emoji-color-fonts

apt-get install fonts-noto-color-emoji

Including a certain symbol from the Google Noto Emoji color font library will 
crash Emacs with "Fatal error 6: Aborted".

see reference: 
https://askubuntu.com/questions/1076735/emacs-crashes-on-pasting-the-unicode-symbol

I was just checking my email in Gnus when this symbol crashed Emacs in X11.  I 
didn't have any issues in terminal mode as the symbol didn't try to render.

Uninstalling the font library prevents the error.
