Iain, could you look at this intermittent RegExp crash.

Flags: needinfo?(iireland)

It looks like this has happened exactly once, and we don't have any crash reports in the wild. This code is pretty deterministic, so by far the most likely explanation is hardware failure.

Unless this starts recurring at a much higher frequency, there's nothing actionable here.

Flags: needinfo?(iireland)
Priority: -- → P5
