values

    (1, 'A123456789', 5, 1, 1, '2018-05-06', 1);

alter table person_principal add column if not exists date_mask tinyint null;

update person_principal set date_mask = 0;

alter table person_principal modify column date_mask tinyint not null;

leads to a crash with the following output:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

The MariaDB-Docker-Image is derived from Ubuntu:bionic, it is the official image from Docker Hub.

Maybe relates to MDEV-21663, MDEV-21800, or ~~MDEV-21787~~

Version 10.4.12 is not affected, if that helps.

Best regars, Jan

    MDEV-20494 ER_NOT_FORM_FILE or assertion upon adding partition to period table

    - Fixed mysql_prepare_create_table() constraint duplicate checking;

    - Refactored period constraint handling in mysql_prepare_alter_table():

      * No need to allocate new objects;

      * Keep old constraint name but exclude it from dup checking by automatic_name;

    - Some minor memory leaks fixed;

    - Some conceptual TODOs.
