Assertion failure i==j on ADD FOREIGN KEY
The following test case triggers a debug assertion failure during ALTER TABLE:
--source include/have_innodb.inc
|
CREATE TABLE t1(a INT PRIMARY KEY) ENGINE=InnoDB;
|
CREATE TABLE t2(a INT PRIMARY KEY) ENGINE=InnoDB;
|
ALTER TABLE t2 ADD FOREIGN KEY(a) REFERENCES t1;
|
DROP TABLE t2, t1;
|

The reason appears to be that an empty column list will be passed for the REFERENCES t1. I would expect that the matching column names be looked up (in this case a) and their data type compatibility be checked before ha_innobase::create() is invoked.
