In MariaDB 5.5 the bug still exists with the following query statistics:

- If executed with index:

MariaDB [test]> show status like 'last_query_cost';
+-----------------+-------------+
| Variable_name | Value |
+-----------------+-------------+
| Last_query_cost | 5117.799000 |
+-----------------+-------------+
1 row in set (0.00 sec)

MariaDB [test]> show status like 'Handler_read%';
+--------------------------+-------+
| Variable_name | Value |
+--------------------------+-------+
| Handler_read_first | 1 |
| Handler_read_key | 0 |
| Handler_read_last | 0 |
| Handler_read_next | 4079 |
| Handler_read_prev | 0 |
| Handler_read_rnd | 0 |
| Handler_read_rnd_deleted | 0 |
