Looks like it could be a dlbi regression.

There are no comments on the crash reports, so pretty much all we have to go on here are the stacks. Not much I can do here, Matt, unless you can think of something from that.
I think this is caused by us not holding strong refs to the Layers in the LayerTreeInvalidation structure and then comparing raw pointers. Holding a strong ref should prevent this from happening.
There are no crashes over the last four weeks.
