Do you have any customizations of the fontsets? No, no fontsets customizations. This whole thing is getting weirder. I've recompiled Emacs w/ "-O0 -g3" and two new things appeared: 1) Invalid read syntax: # Warning (initialization): An error occurred while loading =E2=80=98/Users/zrzka/.emacs.d/init.el=E2=80=99 This is random as well, and it happens frequently (30% of Emacs launches). 2) A new crash happened It is hard to reproduce it in my "while true; lldb ...; done" loop with this error (a lot of manual interventios required), but managed to capture another backtrace: https://gist.github.com/zrzka/7855634a46adeacb2fa7e8f861e39106 All this, purely random, undefined behavior? Recompiled again, this time I've added "-fsanitize=3Daddress" (full flags "-O0 -g3 -fsanitize=3Daddress"), and the first thing (Invalid read syntax #) is gone. Leaving it running for the whole night, to see what's gonna happen now. If it won't reveal anything, I will switch back to "-O0 -g3", and will start bisecting 29.1 -> 29.2 changes.
