@divyenduz did you manage to reproduce that last week? I gave it a quick try, and I can't reproduce the crash.

[pantharshit00]

I was also unable to reproduce this. We have missing migrations in the data collected:

So this is hard to reproduce imo. We also can't trace back the report to anyone so we are blind here.

[divyenduz]

Did you both try it with this specific version of MariaDB?

[tomhoule]

Nope, I tried it with whatever version I had installed. There is a lot going on this cycle for me, so I will try to find the time to try to reproduce this on the right version of MariaDB, but it's unlikely I will get to it very soon.

[divyenduz]

This is easily reproducible with this specific version of MariaDB.

This is easily reproducible with this specific version of MariaDB.

This information should be added to the original issue and issue title then.

[divyenduz]

This information should be added to the original issue and issue title then.

Someone else besides me needs to confirm that. Once that is done, we can change the title

[pantharshit00]

I am unable to reproduce this with this docker image:

# Use root/example as user/password credentials
version: '3.1'

services:

  db:
    image: mariadb:10.1.36
    restart: always
    ports:
      - 3307:3306
    environment:
      MYSQL_ROOT_PASSWORD: root

Schema taken from the error report.

(Edit: Also works fine with 2.4.1)

We recently implemented a fix for default value parsing on MySQL variants. Since then we cannot reproduce this anymore. I am closing this therefore.
