 New Comment:

5.1 is effected too.

<?php
$a = array(array('A'));
//$b = &$a[0];
$a[0][] =& $a[0];
$a[0][] =& $a[0];
$a[0][0] = 'b';
var_dump($a);
$a = null;
$b = null;
?>

The problem is in "$a[0][] =& $a[0];" operator, that creates copy of
$a[0] during fetching lvalue because $a[0] is not a reference and after
fetching rvalue it has refcount > 1.

Dmitry, can you check if you can fix the leaks?

Description:
------------
Sorry I have a very bad english but I think the 'Reproduce code' is
self-describing.

Reproduce code:
---------------
// ---------- This work OK:
$a = array('A', & $a, & $a);
$a[1][0] = 'B';
echo $a[0];   // OK : Show 'B'

// ---------- But this don't work:
$a = array('A');
$a[1] = & $a;
$a[2] = & $a;
$a[1][0] = 'B';
echo $a[0];   // Wrong: Show 'A'

Expected result:
----------------
BB

Actual result:
--------------
BA
