Bug description: memory leak when reassigning object
Description:
------------
I encountered an error while assigning multiple class to an object into
another class.
Suppose to have a class A in which is defined a property. At the begin, I
use the property as an instance of another class B, then I do an 'unset' of
property before creating assigning it an instance of class C.
Reproduce code:
---------------
class B {
# do something
}
class C {
# do something
}
class A {
private $_prop;
function __construct() {
$this->_prop = new B();
}
function Re () {
unset($this->_prop);
$this->_prop = new C();
}
}
$h = new A()
$h->Re();
unset($h);
Expected result:
----------------
I expect it to work correctly (I read a post before where staff said it
has been fixed in version 5.2.x).
Actual result:
--------------
it crashes when calling 'Re' method giving me an error:
Allowed memory size of ... bytes exhausted etc.
