Variables declared after cursors with parameters lose value

Details

    Description

      This problem is repeatable in bb-10.2-compatibility:

      This script:

      SET sql_mode=ORACLE;
      		 
      DROP PROCEDURE IF EXISTS p1;
      		 
      DELIMITER $$
      		 
      CREATE PROCEDURE p1() AS
      		 
        x0 INT:=100;
      		 
        CURSOR cur(cp1 INT, cp2 INT) IS SELECT cp1+cp2;
      		 
        x1 INT:=101;
      		 
      BEGIN
      		 
        OPEN cur(10,11);
      		 
        CLOSE cur;
      		 
        SELECT x0, x1;
      		 
      END;
      		 
      $$
      		 
      DELIMITER ;
      		 
      CALL p1();

      returns:

      +------+------+
      		 
      | x0   | x1   |
      		 
      +------+------+
      		 
      |  100 |   10 |
      		 
      +------+------+

      This is wrong. x1 should stay eqial to 101.
