Description:
------------
When creating a class that extends RecursiveIteratorIterator, it causes
a sefault if the __construct() method of the new class does not call
RecursiveIteratorIterator::__construct().
I'm reporting this bug because I would expect to see PHP throw a fatal
error about RecursiveIteratorIterator::__construct() not being
initalized instead of segfaulting. This happens from the CLI and through
Apache using libphp5.so
The backtrace I have included is from 5.2.2, but I have verified that
it causes a segfault on 5.2.3 as well.

Reproduce code:
---------------
<?php
class foo extends RecursiveIteratorIterator {
private $_bar;
public function __construct($str) {
$this->_bar = $str;
}
public function bar() {
return $this->_bar;
}
}
$foo = new foo("This is bar");
echo $foo->bar();
?>
Expected result:
----------------
Output:
This is bar
Actual result:
--------------
Segmentation Fault
Backtrace:
Program received signal SIGSEGV, Segmentation fault.
