I installed NotoSansJavanese-Regular.ttf and when I type `C-h h' to view
the Javanese script, Emacs immediately crashes. It also crashes when I
just try to insert a character from that script, e.g. `C-x 8 RET #xa9b2
RET'. I've attached the backtrace from gdb produced from the latter.
Emacs also crashes when trying to display a character from the Balinese
script with NotoSansBalinese-Regular.ttf installed. The crashes do not
happen in emacs-27 built without cairo, but characters from the Javanese
and Balinese scripts are displayed there as tofu, as they are in Firefox
(e.g. https://en.wikipedia.org/wiki/Javanese_script), so maybe the fonts
are buggy; and indeed, when I uninstall them Emacs built with cairo does
not crash and the characters are displayed as tofu. But it would be
better for Emacs with cairo not to crash with a buggy font, if possible.
If desired, I can send the fonts.
