TB 8.5a5 Sig 11 core dump on shutdown when compiled with Selfrando

Arch Linux tor-browser-linux64-8.5a5_en-US

Just opened e.g. a TB default home site https://www.torproject.org/ and then closed TB, and the core dump happened. I repeated it twice. No other application was open (no memory stress). So, we know that it is repeatable and it happens on TB close. Unfortunately I did not have debug symbols installed.
