Upon attempting to render Unicode 1f596, st exits.
To reproduce, compile and run the attached test or send the same codepoint to
the screen via any other means.
I'm running Fedora 25 (up-to-date) and st HEAD. Google Noto fonts are
installed. (I mention the latter because st loads one of these fonts,
NotoColorEmoji.ttf, just before rendering fails.) See attached strace excerpt.
