Description:
------------
Running this script seg faults instead of producing a reasonable error.

Reproduce code:
---------------
$dsn         = "mysql:dbname=123;host=localhost";
$dbuser          = "123";
$dbpass          = "123";


   class PDO_Dynamic extends PDO {
       private $dsn;
       private $dbuser;
       private $dbpass;

       function PDO_Dynamic($dsn, $dbuser, $dbpass) {
           $this->dsn = $dsn;
           $this->dbuser = $dbuser;
           $this->dbpass = $dbpass;
           $temp = $this->PDO($dsn, $dbuser, $dbpass);

       }

   }


   $db_read = new PDO_Dynamic($dsn, $dbuser, $dbpass);
   $db_write = new PDO_Dynamic($dsn, $dbuser, $dbpass.'-');


Expected result:
----------------
No error at all expected, or at least some sort of warning/fault

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