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

Hi Jon, this popped up after bug 1502946 landed. Can you take a look at it, please?

[Jon Coppeard (:jonco)]

Attachment: bug1503666-gray-marking

This assertion that's failing relies on the old behaviour of ObjectIsNotGray().

The patch fixes the assertion to only happen if we are not in an incremental GC and updates the comments to hopefully be clearer about what's going on.
