Description:
------------
unset() does not free memory.

In the example, list() is important.

Reproduce code:
---------------
for($i=1;$i<10000000;$i++)
{
        list($b['a']) = array ("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
        unset($b['a'],$b);
}


Actual result:
--------------
PHP Fatal error:  Allowed memory size of 1048576 bytes exhausted (tried to alloc
ate 16 bytes) in /tmp/tours2lite.php on line 28

Fatal error: Allowed memory size of 1048576 bytes exhausted (tried to allocate 1
6 bytes) in /tmp/tours2lite.php on line 28

I can't reproduce it with 4.3.x branch.
