Comment 2

[:Gijs (he/him)]

:mccr8, can you help triage this? This is in Fx::Preferences, but I'm fairly sure it needs to go somewhere else (or at least, I have no idea how to go from the asan info to something concrete in the prefs code).

Comment 3

[Andrew McCreight [:mccr8]]

There's nothing to go on here. It hit an invalid write, then ASan ran out of memory when it tried to run the symbolicator. I think we can just leave it alone for a week and see if it happens again with a stack. If not, we can close it incomplete.
