Description:
------------
If you are using PDO and you try to execute "show columns from `table`" query on Windows, PHP crashes violently and Apache service is shutted down automatically.

All other queries work well.

The bug is reproducible only on some versions of Windows - in this case - Windwos Server 2003.

Reproduce code:
---------------
<?php
    $connection = new PDO('mysql:host=localhost;dbname=dbName', 'theUser', 'thePassword');
    
    $query="SHOW COLUMNS FROM `someTable`";
    
    $result = $connection->query($query);
    var_dump($result);
?>


Expected result:
----------------
Apache crashes - the service is stopped because of too many errors.
