New Comment:
On what OS, are you trying your my example on??
Unfortunately, I dont have the knowledge on installing php on FreeBSD
(I normally install it via the port). Im currently investigating if I
can overcome this.
But I was tinkering with the script this morning.

$array = array(0);
class RecursiveArrayIterator extends ArrayIterator implements
RecursiveIterator {
function hasChildren() {
return (is_array($this->current()));
}
function getChildren() {
return new self($this->current());
}
}
$it = new RecursiveIteratorIterator(new
RecursiveArrayIterator($array));
while($result = $it->valid())
{
var_dump($result);
$it->next();
}
echo "\n\n";
while($result = (bool)each($array))
{
var_dump($result);
}

Notice how the 1st while loop is returning (bool)TRUE *twice*, while
the 2nd loop is returning (bool)TRUE *once*.
$it->valid() should return (bool)FALSE the second time it was run.
Shouldn't it???

Please try using this CVS snapshot:
http://snaps.php.net/php5-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5.0-win32-latest.zip
Works fine here.

Description:
------------
Trying to create a RecursiveArrayIterator class,
using currently available SPL classes.
Its generating this error ->
php in free(): warning: chunk is already free
Apparently it works on win2k ->
http://marc.theaimsgroup.com/?l=php-general&m=110807956115501&w=2
Reproduce code:
---------------
<?php
$array = array(0 => array('world'));
class RecursiveArrayIterator extends ArrayIterator implements
RecursiveIterator {
function hasChildren() {
return (is_array($this->current()));
}
function getChildren() {
return new self($this->current());
}
}
$it = new RecursiveIteratorIterator(new
RecursiveArrayIterator($array));
foreach($it as $key => $val) {
var_dump($key, $val);
}
?>
Expected result:
----------------
$ php -f z.php
int(0)
string(5) "world"
Actual result:
--------------
$ php -f z.php
int(0)
string(5) "world"
php in free(): warning: chunk is already free
