We call strtolower/strtoupper for all 256 ASCII characters, but ASCII is only defined for 128. The failure in these tests on OSX is above 128, which I do not think we should be testing for.
I created a bug for the tests and added a patch to remove testing above 128 chars: https://bugs.php.net/bug.php?id=55546
