Comment(by TobiasBg):

 Maybe we should not change the functions that are used for now (i.e. don't
 replace array_pop() with end()), but just use the temporary locale
 variable part of the suggested solution. After all the issue is raised by
 the call by reference in some versions of PHP and not the used functions.
