      BUG#58985: Assertion tab->quick->index != 64 failed in 
                 make_join_select() in sql_select.cc
      
      Caused by incorrect ASSERT introduced by BUG#58456. Quick selects 
      may have index == MAX_KEY if it merges indices.
     @ sql/sql_select.cc
        Removed ASSERT. Quick selects may have index == MAX_KEY if it merges indices.
