Description

The assertion looks like ~~MDEV-19273~~, but the rest – the location, scenario, affected versions – are completely different.

SET sql_mode= 'STRICT_TRANS_TABLES'; # Only needed for 10.1, in higher versions it is default

CREATE TABLE t1 (a INT);

LOCK TABLE t1 WRITE;

A slightly different test case causes a slightly different stack trace on debug builds. On 10.2-10.4 it's still very similar to the above, just shorter, while on 10.5 it happens in a different function.

CREATE TABLE t1 (a INT);

CREATE TABLE t2 (b INT);

LOCK TABLE t1 WRITE, t2 WRITE;

--error ER_DATA_TOO_LONG

CREATE OR REPLACE TABLE t1 (a CHAR(1)) AS SELECT 'foo' AS a;

# Cleanup

UNLOCK TABLES;

DROP TABLE IF EXISTS t1, t2;
