Commment from piman@ on CL: Have you looked into priming the clusterfuzz bucket in google storage with a seed corpus to get initial coverage?

I will do that before closing this bug.

I added some seeds generated from cc_unittests and gpu_unittests.

It's possible that the cc_unittests seeds (which are based on OOP-R) aren't doing much because the transfer cache isn't initialized.

I got a couple of clusterfuzz bugs shortly after seeding. So I'm going to mark this as fixed for now.
