Description:
I have a table with LIST partitions.
If I insert a value that's in the list, okay.
If I insert a value that's greater than anything in the list, error -- which is okay.
If I insert a value that's smaller than anything in the list, crash.

How to repeat:
mysql> create table t28 (s1 int) partition by list (s1) (partition p1 values in
(2),partition p2 values in (3));
Query OK, 0 rows affected (0.00 sec)

mysql> insert into t28 values (2),(3);
Query OK, 2 rows affected (0.00 sec)
Records: 2  Duplicates: 0  Warnings: 0

mysql> insert into t28 values (4);
ERROR 1030 (HY000): Got error 1 from storage engine
mysql> insert into t28 values (1);
ERROR 2013 (HY000): Lost connection to MySQL server during query
