ehlo,
you can see warnings on 32 bit machine and cmocka tests.
So the simplest reproducer is to use mock
mock --root fedora-21-i386 --resultdir . --rebuild ./sssd-1.13.90-0.fc23.src.rpm
I plan to send patch for cmocka. Therefore there is #ifndef will_return_ptr.
I would like to avoid prefixed version with sss_ because
it might be useful for other cmocka user as well.
