Major Description
I run this script:
CREATE OR REPLACE TABLE t1 (a INT DEFAULT @a:=''); |
INSERT INTO t1 VALUES (); |
ERROR 1366 (22007): Incorrect integer value: '' for column `test`.`t1`.`a` at row 1
|
The error is OK. Looks fine so far.
Now I quit the client, start a new session, and in the new session run this statement again:
INSERT INTO t1 VALUES (); |
The server crashes with the following stack:
