Bug description: Memory leak in array & objects
Description:
------------
When I unset an array containing object, the memory is not freed as
expected. Too much memory is still used.
Reproduce code:
---------------
<?
ini_set('memory_limit','300M');
class a {
}
echo memory_get_usage()."\n";
$a=array();
for ($i=0; $i<=1000000; $i++) {
$a[]= new a();
}
echo memory_get_usage()."\n";
unset($a);
echo memory_get_usage()."\n";
?>
Expected result:
----------------
325776
230042304
circa 325776
Actual result:
--------------
325776
230042304
