            Bug ID: 96638
           Summary: once-test fails
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: build-system

The once-test fails for 8.99 versions

Version-Release number of selected component (if applicable):
pulseaudio-8.99.2-1.fc25

FAIL: once-test
===============
Running suite(s): Once
0%: Checks: 1, Failures: 1, Errors: 0
tests/once-test.c:74:F:once:once_test:0: Assertion
'pthread_setaffinity_np(pthread_self(), sizeof(mask), &mask) == 0' failed
FAIL once-test (exit status: 1)

imo it's a bug in the check which just run the threads on all CPUs even some
CPUS are on active, for example on ppc64/ppc64le in koji (fedora build
enviroment)

i did a patch which resolves this issue for me.
