macOS-only low-volume crasher. This doesn't seem like a new bug, the oldest buildid which has it is 20191202091209, that was when nightly was at version 72. The crash is a NULL-pointer dereference and the lower frames of the stack are always the same but I found at least two separate stacks leading to this issue.

Low-volume, non-obvious. We're going to watch it.
