Different outcome with slightly modified test:

SET SESSION old_mode='';

CREATE TABLE t (a INT) ENGINE=InnoDB;

ALTER TABLE mysql.innodb_index_stats MODIFY stat_description VARCHAR(1024) COLLATE utf8_bin;

DROP TABLE t;

Leads to:

The debug assertion can obviously be violated. I removed it, because we do still report errors in this case.

I did not check it, but I think that a similar error could be possible in earlier versions if the encoding of the column was changed to be utf8mb4.

Had one more testcase for this bug with slightly different uniqueID.

table->cols[j].len < req_schema->columns[i].len|SIGABRT|dict_table_schema_check|dict_stats_persistent_storage_check|dict_stats_update|dict_stats_init

Adding it for completeness.

SET sql_mode='';

CREATE TABLE t (a ENUM ('','') DEFAULT'');

SET SESSION old_mode=no_progress_info;

ALTER TABLE mysql.innodb_index_stats MODIFY stat_description VARCHAR(1024) COLLATE utf8_bin;

INSERT INTO t VALUES (0,0,36,'','','','');

Leads to:
