      Customer claims he wasn't succesfull reproducing the issue outside

    Description

      Hello,

      I have a trouble in examining a customer's issue.
      I have available full backtrace, coredump, specific query on which the server dies, table structure, server log, systemd journal and my.cnf configuration.
      Even though I was unsuccessful solving it yet. It might me much easier for you to help me out. Which I would be grateful for, as the issue solving is really crucial for the customer.

      Backtrace:
