Description:
Use of a variable within a GROUP_CONCAT function within a stored procedure causes a 
crash. Use of a variable within other functions (e.g. MIN/MAX) does not cause a crash. 
 

How to repeat:

mysql> create procedure p () begin declare v2 char(10) default 'b'; select
group_concat(v2) 
from t; end;// 
Query OK, 0 rows affected (0.00 sec)
