branch-nick: maria-5.5

Also reproducible on MySQL 5.5.20 and filed as http://bugs.mysql.com/bug.php?id=64037.
Not reproducible on Maria 5.3, MySQL 5.1.60 , MySQL 5.6.4.

1. Test case:

CREATE TABLE IF NOT EXISTS t ( a INT )
PARTITION BY RANGE ( a ) (
PARTITION p0 VALUES LESS THAN ( 0 ),
PARTITION p1 VALUES LESS THAN MAXVALUE ) ;

ALTER TABLE t DROP PARTITION p1;
ALTER TABLE t ANALYZE PARTITION p0, p1;

ALTER TABLE t COMMENT 'altered';
