Does this still happen under 2.16.3 for you?

Yes, the crash still happens on 2.16.3.

Okay, I'll take a deeper look.

Just to keep you posted, I've finally managed to repro this; it seems to be happening specifically on Radeon GPUs somewhere down in mesa. I have a suspicion of what's going on, but I'm going to be digging in a bit more.

Nothing extracted yet.
