Bug #9715 SP crashes MySQL server if query cache is enabled

Description:
SP crashes MySQL server if query cache is enabled.

mysql> call `dbpos`.`upiaddruntimekeypositions`();
ERROR 2013 (HY000): Lost connection to MySQL server during query
mysql>
Number of processes running now: 0
050407 16:56:12  mysqld restarted

If I disable query cache SP runs like charm.

How to repeat:
1. Start MySQL server with enabled query cache.
2. Restore database from dump
3. Create stored procedure from sp.sql
4. Run: call `dbpos`.`upiaddruntimekeypositions`();

create table t1 (a int);
insert into t1 values (1),(2);

delimiter //;
CREATE PROCEDURE `p1`()
begin
Declare var1 int;
Declare c1 cursor for select a from t1;

open c1;
select * from t1;

end//

call p1()//
