ffmpeg 2.8.6-1 test failures on hppa
Hi,
ffmpeg 2.8.6-1 failed to build on hppa due to test failures [1].
Previous versions worked fine [2] and since not much changed in ffmpeg, I'm
assuming it's actually a regression in gcc-5 5.3.1-7.
Note that this version of gcc-5 also regressed on mips [3].
Among the many test failures, the following is most interesting:

Test crc failed. Look at tests/data/fate/crc.err for details.
So all computed crc values are wrong. It's not surprising that this crc mismatch
causes many other tests to fail.
It would be great if someone with the necessary hardware could investigate
what causes this problem.
Best regards,
