Description:
------------
If you call register_shutdown_function, and then in the registered
function make a call to PHP Exception, Apache segfaults.  

Here's a sample script:

Reproduce code:
---------------
class	DodService
{
    private     $connexion;

    function    __construct()
    {
        register_shutdown_function(array($this, "out"));
    }
  
    function out()
    {
        throw new SoapFault("ERROR", "Internal Server Error.");
        return true;
    }
}    

Actual result:
--------------
