Bug description: Exception raised in an iterator::current() causes segfault in

When raising an exception in the current() method of an iterator while
that iterator is being processed by either an IteratorIterator or
FilterIterator causes PHP to crash.
Reproduce code:
---------------
<?php
class BlaIterator implements Iterator
{
public function rewind()
{
}
public function next()
{
}
public function valid()
{
return true;
}
public function current()
{
throw new Exception('boo');
}
public function key()
{
}
}
$it = new BlaIterator();
$itit = new IteratorIterator($it);
foreach ($itit as $key => $value)
echo $value;
Expected result:
----------------
Exception thrown
Actual result:
--------------
