Created php tracking bugs for this issue:

Statement:

This issue did not affect the versions of php and php53 as shipped with Red Hat Enterprise Linux 5 and the versions of php as shipped with Red Hat Enterprise Linux 6 and 7.
Comment 3 Stefan Cornelius 2015-08-25 10:38:24 UTC 
Seems like this is a PHP7 only issue. None of the php versions we ship should be affected.
