Bug description: PHP segfaults when an exception is thrown in getIterator()
within foreach
Description:
------------
When an object implementing IteratorAggregate is used within a foreach
loop, PHP will segfault if an exception is thrown within getIterator().
Reproduce code:
---------------
<?php
class Iter implements IteratorAggregate {
function getIterator() {
throw new Exception('exception');
}
}
$test = new Iter();
foreach($test as $val)
echo "foo";
?>
Expected result:
----------------
Fatal error: Uncaught exception 'Exception' with message 'exception' in
/home/benj/projects/bugs/spl_foreach.php:5
Stack trace:
#0 {main}
thrown in /home/benj/projects/bugs/spl_foreach.php on line 5
Actual result:
--------------
Segmentation fault (core dumped)
