1680916 - Windows 32-bit facebook.com Crash in [@ OOM | large | mozalloc_abort | alloc::raw_vec::RawVec<T>::allocate_in<T>]

Status: RESOLVED DUPLICATE of bug 1531819

(Core :: Graphics: WebRender, defect)

Description

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

32-bit only crash new in 84.0 betas (starting with beta 1). Windows 10 is also affected and sees the majority of crashes.

Most of the crashes hit when the user has https://www.facebook.com open (based on the reports where the person submitted the url).

Matt, please evaluate what should be done for Firefox 84 here (this week the release candidates are being built).

[Ryan VanderMeulen [:RyanVM]]

Probably too late to address in 84, but let's keep an eye on it in case it spikes on release.

Comment 2

[Jeff Muizelaar [:jrmuizel]]

Is this perhaps just a signature change?

Comment 3

[Jeff Muizelaar [:jrmuizel]]

I think this is probably the same as bug 1531819

Comment 4

[Ryan VanderMeulen [:RyanVM]]

Sure looks like it, thanks for checking.
