This change addresses one of two problems: that this function crashes when passed anything but a reference as a 4th parameter. Another problem is that it's possible to trick PHP into passing a non-reference with defined(), but it will be addressed separately. The solution in this change is applicable to other functions, they will be upgraded later.
