Description:
------------
The code reported causes an apache crash.

It happens only with persistent connection, if i set PDO::ATTR_PERSISTENT = false, the script works fine.

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

try {
    $dbo = new PDO(
                        'mysql:host=localhost;dbname=test',
                        'user',
                        'pass',
                        array(PDO::ATTR_PERSISTENT => true)
                    );
} catch(PDOException $e) {
    echo 'Errore di connessione: '.$e->getMessage();
}

$pdostatement = $dbo->prepare('SELECT * FROM fake_table');
$pdostatement->execute();

echo 'print something';

?>

Expected result:
----------------
The script should just print out 'print something'.

Actual result:
--------------
Apache crash, this is the error in apache error.log: 

Sun Nov 27 00:48:48 2005] [notice] child pid 3051 exit signal Segmentation fault (11)
