Description:
------------
Throwing through Reflection modified Exception (or any other Exception
type) object makes php segment fault when file property is set to null.



Reproduce code:
---------------
<?php
$e = new Exception();
$reflection = new ReflectionObject($e);
$property = $reflection->getProperty("file");
$property->setAccessible(true);
$property->setValue($e, null);
throw $e;
?>

Expected result:
----------------
PHP Fatal error:  Uncaught exception 'Exception' in null:xx

Actual result:
--------------
Segmentation fault


------------------------------------------------------------------------
