Description:
INSERT IGNORE should set an appropriate warning for each record that could not be added to the table (so that these may be found using SHOW WARNINGS).

How to repeat:
mysql> create table t (i int primary key not null);
Query OK, 0 rows affected (0.00 sec)

mysql> insert ignore into t values (1), (1), (1), (1);
Query OK, 0 rows affected (0.00 sec)
Records: 4  Duplicates: 4  Warnings: 0

There is of course an

insert into t values (1);

missing in between the two how-to-repeat statements
