Description:
------------
It seems that prepared statements with bindValue (or bindParams) don't work as expected. The two examples below should output the same things.

Configuration : 
PHP 5.1.6 (ubuntu package)
MySQL 4.1.15 (ubuntu package)
PDO_MYSQL compiled with libmysqlclient14-dev (header for MySQL 4.1) and libmysqlclient15-dev (header for MySQL 5.0) with the same result.

Reproduce code:
---------------
test_pdo.php
<?php
$db = new PDO('mysql:host=localhost;dbname=sew', LOGIN, PASSWORD);
$stmt = $db->prepare('select * from `sew_sites` where `id`=:id');
$stmt->bindValue(':id', 1);
$stmt->execute();
$row = $stmt->fetchAll( PDO::FETCH_ASSOC );
var_dump($row);
$stmt->closeCursor();
?>

test_pdo_simple.php
<?php
$db = new PDO('mysql:host=localhost;dbname=sew', LOGIN, PASSWORD);
$stmt = $db->prepare('select * from `sew_sites` where `id`=1');
$stmt->execute();
$row = $stmt->fetchAll( PDO::FETCH_ASSOC );
var_dump($row);
$stmt->closeCursor();
?>

Expected result:
----------------
These two scripts should output exactly same data.

Actual result:
--------------
