[Phalcon Pdo] Strange error when I try to fetch result as column

[oswebex]

I can't fetch result as column, but if directly use PDO then the result is right.
And I got a strange error.

SQLSTATE[HY000]: General error: colno must be an integer

Provide minimal script to reproduce the issue

$list = $this->db
  ->fetchAll('SELECT id FROM tbl WHERE status = -2', \Phalcon\Db::FETCH_COLUMN);

// or

$result = $this->db->query('SELECT id FROM tbl WHERE status = -2');
$result->setFetchMode(\Phalcon\Db::FETCH_COLUMN);
$list = $result->fetchAll();

// directly PDO work well
$list = $this->db->getInternalHandler()
  ->query('SELECT id FROM tbl WHERE status = -2')
  ->fetchAll(PDO::FETCH_COLUMN);
