Description:
If I make a partition which depends on an expression which
contains a column which has character set UTF8, crash.

How to repeat:
mysql> create table t33 (s1 char(2) character set utf8) partition by list (case when s1 > 'cz' then 1 else 2 end) (partition p1 values in (1),partition p2 values in (2));
Query OK, 0 rows affected (0.01 sec)

/* At this point, despite the "OK" message, the server is gone. */

Looking at the trace, it crashes outside of partitioning on Query_arena::free_items
