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> delimiter // mysql> create table t (s1 char(10))// Query OK, 0 rows affected (0.31 sec) mysql> insert into t values ('a'),('b')// Query OK, 2 rows affected (0.00 sec) Records: 2 Duplicates: 0 Warnings: 0 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) mysql> call p()// ERROR 2013 (HY000): Lost connection to MySQL server during query
