Description:
------------
Throwing any error in foreach causes PHP to crash since PHP 5.1.3

Test script:
---------------
class MyFilterIterator extends FilterIterator
{
	function accept() { return TRUE; }
}

$iterator = new RecursiveArrayIterator(array(1));
$iterator = new RecursiveIteratorIterator($iterator);
$iterator = new MyFilterIterator($iterator);

foreach ($iterator as $component) {
	trigger_error('User error', E_USER_ERROR); 
        // or trigger fatal error by calling undefined function xyz()
}

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

I can't reproduce this on OS X or Linux. Besides needing a backtrace,
we'll also need to know what operating system you're running.

I am sorry, this bug affects only 5.1.3 - 5.3.2 and is fixed in 5.3.3.
