If it fails again, I'll take a closer look. Yes, there seems to be a gcc bug/problem. I've manually rebuilt ffmpeg-2.8.5-1 with gcc-5_5.3.1-8 and it fails the same way (but it built earlier with gcc-5_5.3.1-6). So, gcc-5_5.3.1-7 (and higher) currently have the problem. Problem is (like you said) somewhere in the md5/crc code: TEST api-flac /<<PKGBUILDDIR>>/tests/fate-run.sh fate-api-flac "" "" "/<<PKGBUILDDIR>>/debian/standard" 'run tests/api/api-flac-test' 'null' '/dev/null' '' '1' '' '' '' '' '' '' '' '' /<<PKGBUILDDIR>>/debian/standard/tests/api/api-flac-test Test api-flac failed.
