ccameron@: Could you please take a look into this if its related to your change.

I don't think so.

Jamie, can you take a look?

Sure. The crash is in command buffer somewhere so it's not my area of expertise but if it's not a high priority issue can follow up.

Then let me take this.  I saw it's gpu_angle_fuzzer and thought it's in ANGLE.

No problem, I thought maybe that was the case. Feel free to send it back at any point.
