InnoDB fails to rollback after exceeding FOREIGN KEY recursion depth

    Details

      Description

      Note: Possibly it is related to the numerous existing bugs known as "MDEV-9663 family" or MDEV-14643 family". But there have been false relations before, I don't want to pollute the bug reports any further, so I'm filing this one separately. If you find a true relation, feel free to close this one as a duplicate.

      On 10.2-10.4 RelWithDebInfo builds it produces numerous errors and eventually the very same assertion failure:
