PHP Bug Type: Scripting Engine problem
Bug description: __set() leaks memory
Description:
------------
__set() seems to leak memory when extending internal classes
(DOMElement for instance)
Reproduce code:
---------------
<?php
class foo extends DOMElement {
private $a = array();
public function __construct() {
}
public function __set($k, $v) {
$this->a[$k] = $v;
}
}
$obj = new foo;
$obj->foo = "bar";
Actual result:
