Bug#892611: emacs: crash when buffer contains ⛅ (u+026c5)

[me]

It seems to be a problem with emoji in general. I had same crash but 
with different symbol (⏱ U+23F1). I had package "fonts-noto-color-emoji" 
installed, removing it caused crashes to stop. Probably it's possible to 
make a fontconfig rule to make emacs not use that font.
