Bug description: several leaks appear when changing the result of __get()
Description:
------------
Several leaks appear in the reproduce code.
The code itself is quite weird (and cannot work), but still..
Reproduce code:
---------------
<?php
class test {
public function __get($var) {}
}
$test = new test();
$test->a["b"]["c"] = "";
?>
Expected result:
----------------
Notice: Indirect modification of overloaded property test::$a has no
effect in ..
Actual result:
--------------

lost in loss record 1 of 2
