I've been hit twice recently by Address Sanitizer bugs (#20237, #19851).
It's always a huge pain to figure out what's happening, and then to work
around it. I had to grab an old glibc and hack around with $LD_PRELOAD for
one, screw around with ulimits for the other. And I need to boot a Tails
VM to get a working browser to search for the error messages (which aren't
even printed by default), and then copy/paste is difficult.
start-tor-browser should have a documented option to disable ASan. And the
script shouldn't just clobber ASAN_OPTIONS if it's set, because that just
complicates debugging (prepend/append your string instead).
