Is this sufficient info?

Regrettably no debug symbols in the Docker builds, unless I missed something.

Thank you in advance.

Hi!

Unfortunately we weren't able to use the core file you sent. Can you enable log_debug=category=debug in config file (you can put it in your local.conf) and try again, this hopefully produces more information.
