      The test case from which this results is:

      #
      # Table sizes are approximations and for this particular case we allow about
      # 10% deviation.
      #
      if ($diff < 6000) {
        select table_name from information_schema.tables where table_schema = database() and table_name = 't2';
      }
      

      So maybe 6000 isn't enough?

      Oddly doesn't occur on amd64-windows-packages where it is frequently tested.
