Different assertion with this testcase:

SET sql_mode='', unique_checks=0, foreign_key_checks=0, autocommit=0;
 
CREATE TABLE t (PRIMARY KEY(a)) (SELECT 1 AS a) UNION ALL (SELECT 1 AS a);
 
CREATE TABLE t (c INT) ENGINE=InnoDB;
 
DROP TABLE IF EXISTS t;
 
CREATE TABLE t2 (c INT) ENGINE=InnoDB;
 
CREATE TABLE t (pk INT PRIMARY KEY);
 
INSERT INTO t SELECT b.SEQ FROM seq_1_to_128,seq_1_to_1024 b;

Leads to:

10.9.0 b5852ffbeebc3000982988383daeefb0549e058a (Debug)

 
InnoDB: Failing assertion: i > 0

Another stack/assertion

SET unique_checks=0,foreign_key_checks=0,autocommit=0;
 
CREATE TABLE t (c INT) PARTITION BY KEY(c);
 
INSERT INTO t VALUES (1),(1);
 
SET SESSION foreign_key_checks=1;
 
SHOW CREATE TABLE t;
 
CREATE TABLE t (d INT);

Comment by Marko Mäkelä [ 2022-02-21 ]

I think that the KEY in the second CREATE TABLE statement is interpreted as PRIMARY KEY.

I do not necessarily agree that it is a critical bug if a user promises that there are no duplicates (SET unique_checks=0) and then goes ahead and inserts duplicates, and then something bad happens.
