      This query:

      SELECT 1 UNION SELECT *  FROM t1 PROCEDURE ANALYSE();

      is disallowed by this code:

      procedure_clause:
      		 
        ...
      		 
        if (&lex->select_lex != lex->current_select)
      		 
        {
      		 
          // SELECT * FROM t1 UNION SELECT * FROM t2 PROCEDURE ANALYSE();
      		 
          my_error(ER_WRONG_USAGE, MYF(0), "PROCEDURE", "subquery");
      		 
          MYSQL_YYABORT;
      		 
        }

      It should be disallowed syntactically.
