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

The Bugbug bot thinks this bug should belong to the 'Core::JavaScript: GC' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

[Andrew McCreight [:mccr8]]

Looks like a plain old OOM during a nursery collection. I did a proto signature search on crash stats, and it looks like this is bug 1472062. Or you could undupe it and move it to the crash reporter component if you want to make this be about the poor signature.

These crashes should magically move to the better signature with the patch from bug 1843354.
