[PATCH][ZE1] (resend) fix for bug #19943

Hi,

Could anyone review this patch again? (I sent this one before the release 
of 4.3.0 actually.) The patch is against ZE1 and addresses memleaks that 
occur when brackets are used to access an element in a string like below.

patch:
http://marc.theaimsgroup.com/?l=php-dev&m=103654899426422&q=p3

snippet:
<?php
$ar = array();
for ($count = 0; $count < 10; $count++) {
    $ar[$count]        = "$count";
    $ar[$count]['idx'] = "$count";
}

for ($count = 0; $count < 10; $count++) {
    echo $ar[$count]." -- ".$ar[$count]['idx']."\n";
}
?>

Regards,
Moriyoshi
