I'm seeing a few unit tests (as run with "make check") fail on non-x86 hardware, specifically ppc64le and aarch64.
These looks to be just slight accuracy differences and may be chalked up to functional differences in hardware. I don't see any tolerance controls for these tests to account for differences like these. It would be nice if there were.

I think these two distro reports are related, although one of them is on x86_64:
