Merge branch 'PHP-5.6'

* PHP-5.6:
  the darwin specific test fails for me with the same output which is the expected for the original test I couldn't find anybody who managed to see this test passing, but I found a bunch of other reports on qa.php.net/reports and on google which do see this test failing on mac. if this change causes you to have this test failing on Mac, please drop me a mail so we can improve the current test so it passes for everybody.
  5.5.21 now
