    Description

       
      		 
      create table t1 (c1 int, c2 int, c3 int);
      		 
      create table t2 like t1;
      		 
       
      		 
      with d3 (a1, a2, a3) as (select * from t1 union select * from t2 order by c1) select * from d3;

      ERROR 1054 (42S22): Unknown column 'c1' in 'order clause'

      code in st_select_lex_unit::prepare() is renaming columns in the select_lex before name resolution happens (in this case setting up order).
