Description:
I create a partitioned table.
The table has a unique column, which is also the partition-by column.
I try to add another partition.
I get an out-of-memory error.

How to repeat:
mysql> create table tpax (s1 int, unique (s1)) partition by list (s1) (partition                              x1 VALUES in (10), partition x2 values in (20));
Query OK, 0 rows affected (0.04 sec)

mysql> alter table tpax add partition (partition x3 values in (30));
ERROR 1037 (HY001): Out of memory; restart server and try again (needed 8 bytes)

Thank you for the bug report.
