Description:
------------
This is similar to the closed bug #40913, but I have a different OS and a newer 
PHP version.

It still exists in PHP 5.4.8.

I am relatively new to the bug system, if this is considered a duplicate, please 
close this and reopen #40913.

Test script:
---------------
$stmt = $pdo->prepare('SELECT blobfield FROM filetable');

$rset = $stmt->execute();

$rset->bindColumn(1, $blob, PDO::PARAM_LOB);

$rset->fetch(PDO::FETCH_BOUND);

echo gettype($blob);

Expected result:
----------------
resource

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