Description:
------------
When I construct an object I expect an exception to be thrown when there's any 
problem. Still, on Windows 8 I get the Fatal Error with no message, while 
expecting Fatal Error: Uncaught Exception. Moreover, if \PDOException is caught 
and any other type exception is thrown, normal Fatal Error: Uncaught Exception 
<bla bla bla> appears.

Test script:
---------------
<?php
/**
 * an empty Fatal Error appears
 */
$pdo = new \PDO('mysql:host=localhost;dbname=test','user','password');

/**
 * an expected Fatal Error Uncaught Exception apperas
 */
try {
   $pso = new \PDO('mysql:host=localhost;dbname=test','user','password');
} catch(\PDOException $ex) {
    throw new Exception('\PDO Exception\'s been caught!');
}

/**
 * an empty Fatal Error appears again
 */
try {
    $pso = new \PDO('mysql:host=localhost;dbname=test','user','password');
} catch(\PDOException $ex) {
    throw new Exception($ex->getMessage());
}   

Expected result:
----------------
Fatal Error: Uncaught Exception '\PDOException' with message '<message goes here>'
in test.php on line 5

Actual result:
--------------
Fatal Error: in test.php on line 5
