    Description

      Setting it to Minor, as it only seems to affect debug builds of 10.1-10.2 (and probably earlier versions, but they are no longer supported), but not 10.3+.

      The test case is non-deterministic, run with repeat=N. It fails fairly well for me, usually within several attempts.

      Reproducible on 10.1-10.2. Couldn't reproduce on 10.3+.
      It is possible that the underlying problem was fixed (or masked!) at some point in 10.3+ by some other changes. It would explain why MDEV-18833, which was originally filed for 10.3+, doesn't seem to be reproducible anymore.

      The test case can be varied to make it fail on a SELECT instead (note extra setting for transaction isolation level):
