Description:
------------
When a class definition contains any reference to a variable name that will be later used in a __set() (or __get()) operation, the setter (or getter) will not fire.

This variable does not have to be defined or used at all. The code must simply exist.

In the following example code, simply comment out the print($this->myVar); line and you will see the 'setter fired' message.

This is NOT similar to bug #24608 as the element never gets created in this case.

Reproduce code:
---------------
class test {
  function unusedFunction() {
    print($this->myVar);  
  }
  function __set($nm, $vl) {
    print('setter fired');
  }
}

$obj = new test();
$obj->myVar = 'some data';

Expected result:
----------------
'setter fired'


Actual result:
--------------
Nothing.
