Bug description:  using PDO::query() more than once 

Description:
------------
If I want to use PDO::query() more than one time in a script, I have to
set the last PDOStatement to NULL, before I can use the second query. Only
If I add:

$stmt1 = NULL;

before

$stmt2 = $db->query ...

in the example below, I can work with the second query. 

But - how can I work with two statments at the same time? I often have to
do this! I don't understand it because I use two different variables for
the statements here.

I have used the pdo_mysql driver (MySQL 4.1.14), pdo and pdo_mysql were
compiled from latest CVS.

Reproduce code:
---------------
<?php
$db = new PDO('...');

$stmt1 = $db->query('SELECT * FROM table1');
var_dump($stmt1);

$stmt2 = $db->query('SELECT * FROM table2');
var_dump($stmt1);
?>

Expected result:
----------------
object(PDOStatement)#2 ...
object(PDOStatement)#2 ...

Actual result:
--------------
object(PDOStatement)#2 ...
bool(false)
