      Description

      Following query results in exception at run time in vector mode.

      explain select n_name from supplier_orc s join ( select n_name, n_nationkey from nation_orc n join region_orc r on n.n_regionkey = r.r_regionkey and r.r_name = 'XYZ') n1 on s.s_nationkey = n1.n_nationkey;
      

      Here n_name is a string and all other fields are int.

      The stack trace:
