Description:
------------
PDO gives an inconsisten error message when I use the new PDO::ATTR_DEFAULT_FETCH_MODE in combination with PDO::FETCH_INTO.

Reproduce code:
---------------
<?

$pdo = new PDO ('sqlite::memory:');

$pdo->exec ("create table test (id integer primary key, n text)");
$pdo->exec ("INSERT INTO test (n) VALUES ('hi')");

$pdo->setAttribute (PDO::ATTR_DEFAULT_FETCH_MODE, array (PDO::FETCH_INTO, $a));
$stmt = $pdo->prepare ("SELECT * FROM test");
$stmt->execute();
var_dump($stmt->fetchAll());


Expected result:
----------------
i don't know exactly

Actual result:
--------------
Warning: PDOStatement::fetchAll() [function.PDOStatement-fetchAll]: SQLSTATE[HY000]: General error: PDO::FETCH_LAZY can't be used with PDOStatement::fetchAll() in ... on line 11
bool(false)
