[Marcia Knous [:marcia]]

Updating flags since this crash is present on 68/67/66. Also changing platform since it happens on Mac as well.

Comment 2

[Andrei Purice]

Marking this as Resolved > Worksforme since there are no more crashes with this signature in the past 6 months.

Comment 3

[Calixte Denizet (:calixte)]

Unfortunately, nowadays, the signature is still there, so I reopen this bug.

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

I guess that it's resurrected by Fission work or something touching IPC timings. Another reason crash is reported as bug 1690827.

Comment 5

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Crash rate (= diagnostic asserts) for this changed from 1-2 crashes per beta for Firefox 114 to ~10-15 for Firefox 115.

Masayuki, could you check why the volume increased and if anything needs to be done?

It's caused by a regression of the fix of bug 1690827. Now, the follow up patch is landed. So, the crash rate should be go down to 0.

Comment 7

[BugBot [:suhaib / :marco/ :calixte]]

The bug is linked to a topcrash signature, which matches the following criterion:

:edgar, could you consider increasing the severity of this top-crash bug?

It seems that this is now completely fixed in bug 1690827.
