(In reply to Jens Stutte [:jstutte] from comment #2)

I think this is the ASAN version of bug 1833503 ?

Maybe, fwiw reports from the fuzzers just spiked.

Verified bug as reproducible on mozilla-central 20230614213601-933dd3c3e1c8.
The bug appears to have been introduced in the following build range:

Start: 99e2e426103b16eaa9331b269fb38be0eae943df (20221101193641)
End: 99e2e426103b16eaa9331b269fb38be0eae943df (20221102044132)
Pushlog: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=99e2e426103b16eaa9331b269fb38be0eae943df&tochange=99e2e426103b16eaa9331b269fb38be0eae943df

Keywords: regression
Whiteboard: [bugmon:bisected,confirmed]

Hrmm. Bisection range is wrong. The start and end revisions are the same but we have two different build IDs. Not sure how that happened.
