Group_concat order by with long double fails

    Details

    • Sprint:
      2020-5, 2020-6, 2020-7

      Description

      A group_concat call with a subselected SUM (or AVG) in the order by phrase wil fail with
      "ERROR 1815 (HY000): Internal error: IDB-2035: An internal error occurred. Check the error log file & contact support."

      debug.log will contain "/home/calpont/mariadb/engine/utils/rowgroup/rowgroup.h@726: assertion '0' failed"

      The problem is that the order by portion of group_concat is not long double aware.
