Bug #6127 Stored procedure handlers within handlers don't work

Description:
In a stored procedure, I define a handler for a condition X. Within the handler, there is a 
handler for another condition Y -- that is, a "nested handler". I execute a statement which 
causes activation of the handler for X. In the body of this handler, I execute a statement 
which should cause activation of the handler for Y. But the handler for Y is not activated. 
The statement fails. 
 

How to repeat:
mysql> create table t7 (s1 int unique)// 
Query OK, 0 rows affected (0.29 sec) 
 
mysql> set sql_mode='traditional'// 
Query OK, 0 rows affected (0.00 sec) 
 
mysql> create procedure p18 () 
    -> begin 
    ->   declare continue handler for sqlstate '23000' begin 
    ->     declare continue handler for sqlstate '22003' insert into t7 values (0); 
    ->     insert into t7 values (1000000000000000); 
    ->     end; 
    ->   insert into t7 values (1); 
    ->   insert into t7 values (1); 
    ->   end; 
    ->   // 
Query OK, 0 rows affected (0.00 sec) 
 
mysql> call p18()// 
ERROR 1264 (22003): Out of range value adjusted for column 's1' at row 1
