I looked into it, and I've found you really got a point.
---------------------------
<?php
$ragged = array();
$ragged[0] = "a";
$ragged[0][0] = array("1");
var_dump($ragged);
?>
---------------------------
The first script causes no leaks, while the second does:
---------------------------
<?php
$ragged = array();
$ragged[0] = "a";
$ragged[0][0] = (string)array("1");
var_dump($ragged);
?>
---------------------------
Thanks for your insight.
