This started suddenly around 11/27 and so is likely a regression from something that landed around then.

Also interestingly it's Windows PGO only; I see no non-PGO builds in Orange Report.  This might point at a compiler issue.

Not sure who should be involved from the PGO side

The first instance on fx-team and m-c both are pointing at this range:
https://hg.mozilla.org/mozilla-central/pushloghtml?changeset=47b49b0d3236

I have this crazy suspicion that it's from https://hg.mozilla.org/mozilla-central/rev/ec6611006fd0 - more specifically, the adding of a new test messing around with timings or something.

I'd blame the cubeb update, but that was backed out. Don't see any other obvious culprits in that range. I'll run some retriggers on inbound to hopefully confirm.

Also, FWIW, OrangeFactor says that this also affects Win7 and that both Opt & PGO are affected.
A little retriggering says the failure rate on Win !debug is around 20%. That's rather a lot too much.
