Testcase crashes using the initial build (mozilla-central 20231113215623-a517db1d17ab) but not with tip (mozilla-central 20231124214933-8a861d9d1b4a.)

The bug appears to have been fixed in the following build range:

Start: 36c4a38c6d225c7315445718e62d4703c40c277a (20231120194812)
End: 7b567ceeead73f84de62ab77b4b6c87450b347fa (20231120230927)

jkratzer, can you confirm that the above bisection range is responsible for fixing this issue?

:nical, I'm assuming that bug 1865585 was responsible for fixing this issue?

Comment 8

[Nicolas Silva [:nical]]

It probably affected it, but I'm still seeing more or less the same stack trace pop up randomly on CI so I don't think it's actually fixed.

Comment 9

[Nicolas Silva [:nical]]

This is now fixed.
