When using an older Version of MariaDB (mariadb:11.2) it works again.

Probably related to https://github.com/php/php-src/issues/13452

[nickygerritsen]

Thanks! I wonder if waiting for an upstream fix is the best thing to do for now? Or alternatively, shall we specify a specific MariaDB version in the proposed docker compose file?

[spitzlei]

From administrators sight: Keep the issue open, the Workaround can be found here. I had some other systems with different languages (python for example) with the same issue with the new MariaDB Image. So I think there will be a quick fix. Someone just has to track it and do the repackaging when the fix is out.

But I can't speak for other users :)

[vmcj]

@spitzlei I'll close this for now as we didn't receive new reports (so I suspect the MariaDB team fixed something).
