The patch developed for BUG#19122 solves this one as well

Description: Attempt to reorganize an existing MyISAM partitioned table to split partitions causes crash. How to repeat: CREATE TABLE `t1` ( `c1` int(11) DEFAULT NULL, `c2` varchar(30) DEFAULT NULL, `c3` date DEFAULT NULL ) ENGINE=MyISAM DEFAULT CHARSET=latin1; *** fill with 8 million rows *** mysql> alter table t1 -> partition by range (year(c3)) -> (PARTITION p5 VALUES LESS THAN (2000), PARTITION p10 VALUES LESS THAN (2010)); mysql> alter table t1 -> reorganize partition p5 into -> (PARTITION p1 VALUES LESS THAN (1996), -> PARTITION p2 VALUES LESS THAN (1997), -> PARTITION p3 VALUES LESS THAN (1998), -> PARTITION p4 VALUES LESS THAN (1999), -> PARTITION p5 VALUES LESS THAN (2000)); Crash...
