Looks like this is a crash that we expect which we can learn from the call stack.

Flags: needinfo?(jdemooij)

This is likely a result of bug 1547649, a change in (OOM) signature but not a new issue.

Component: JavaScript Engine → Javascript: WebAssembly
Flags: needinfo?(jdemooij)
Severity: -- → S3
Priority: -- → P3

Yeah, this is not a bug, it's a deliberate panic resulting from no memory available in a situation where propagating the OOM is pointless -- we'll panic with a less descriptive error subsequently.

Not sure what the proper resolution is here -- close as WONTFIX or INVALID? Leave it open but lower it to P5? These panics are common during testing but we're not going to attempt to fix anything here.

I think closing as WONTFIX/INVALID would be the appropriate thing to do since we don't actually consider this a bug/defect

MANY multiple crashes pointing at this one today.

Crash signatures?

I just cleared them all. I thought you see those on your end. Thanks anyhow.

For what it's worth, I'm sure there will be plenty more coming.
