Bug description: DBLIB driver wont free statements
Description:
------------
As stated on the summary, PDO DBLIB driver wont free memory
allocated to statements (or the resultset, not sure). Same
code done with ext/mssql functions works, though.
Reproduce code:
---------------
$db = new PDO('dblib:host=hostname;dbname=database', 'user', 'password');
$query = 'SELECT GETDATE()'; // NOW() on mysql
for ($i = 0; $i < 10; $i++) {
$stmt = $db->query($query); // new statement
$stmt->fetch(); // actual data
$stmt->fetch(); // false; end of resultset
$stmt->closeCursor(); // this should at least free it, right?
$stmt = null; // being paranoid here
echo memory_get_usage() . "\n";
}
Expected result:
----------------
