Description

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

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

• Top 20 desktop browser crashes on beta

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

This looks like a duplicate of bug 1794059; the crash is handled differently in parent vs. child processes, probably for historical reasons.

I don't have a full explanation for why bug 1794059 appeared immediately but this form of the crash appears to be more recent; maybe there was a signature change? In any case this is likely to be an OOM and we may not be able to do much about it.
