Description:
------------
I came across a very odd bug in 4.3.10 (and 4.3.11).  It's not in 4.3.4, and it's not in 5.0.4.

My understanding is that in 4.x objects are assigned by value.  So, why in the first part of the code is the output of serialize() indicating a reference?  This would suggest that objects are being copied by reference.

But in the second when I change $ary[1]->name, the output of the serialize only changes the second element, not both.  Also, changing $obj->name doesn't have any effect on $ary[0] or $ary[1]. Which would suggest that $ary[0] and $ary[1] are NOT the SAME thing.

The output below is from 4.3.11.  4.3.4 does not have this problem and the serialize() output does not indicate any reference.

In 5.0.4, the everything works like I'd expect it to since objects are assigned by reference.

It's almost like $obj is partially being copied by reference and that serialize is picking up on that or something...

Reproduce code:
---------------
<?php

$obj->name = "Homer";
$ary[] = $obj;
$ary[] = $obj;

$obj1->name = "Homer";
$ary[] = $obj1;

print_r($ary);
print("\n");
print ( serialize($ary) );

print("\n\n---------------------------------------\n\n");

unset($obj); unset($obj1); unset($ary);

$obj->name = "Homer";
$ary[] = $obj;
$ary[] = $obj;

$obj1->name = "Homer";
$ary[] = $obj1;

$ary[1]->name = "Marge";

print_r($ary);
print("\n");
print ( serialize($ary) );

?>


Expected result:
----------------
I would expect to *not* see any indications of references (i.e. "r:2") in the serialized output.

Actual result:
