I'd rather just disable the test, this patch has like 20 others that depend on it so we'd need to revert all of those. It's definitely not grabbing the bitcode from the cache as expected. I can disable this part of the test for now, but do you know how I could figure out how to reproduce this? I've been tracking some other buildbots and they don't seem to have the same issue so I'm not sure what's special about this one.
