Description:
------------
A funny Exception is raised by SplFileObject on certain special situation.

Reproduce code:
---------------
<?php

//yes, get_included_files() is important for the test !!
if(count(get_included_files()) === 1) {

    // yes, **wrong** (mistyped) wrapper.
    $stdout = new SplFileObject('php://stdoutd', 'wb');
}
?>

Expected result:
----------------
PHP Fatal error:  Uncaught exception 'RuntimeException' with message 'SplFileObject::__construct(php://stdoutd): failed to open stream: (Invalid Wrapper ? , File not found ?  or something ;) )

Actual result:
--------------
PHP Fatal error:  Uncaught exception 'RuntimeException' with message 'SplFileObject::__construct(php://stdoutd): failed to open stream: **Success**

or in other cases without the get_included_files() call I get 
"Inappropriate ioctl for device" (!!)
