ALTER TABLE wrongly checks for field's default value if AFTER is used

Details

    Description

      See the following test script:

      CREATE TABLE test(
      		 
      t text NOT NULL,
      		 
      d date NOT NULL
      		 
      );
      		 
       
      		 
      insert into test values ("x",CURRENT_DATE());
      		 
       
      		 
      SET SESSION sql_mode = "STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION,NO_ZERO_DATE,NO_ZERO_IN_DATE";
      		 
       
      		 
      ALTER TABLE test
      		 
      CHANGE d d DATE  NOT NULL AFTER t,
      		 
       ADD i text NOT NULL AFTER d
      		 
      ;

      Resulting in
      Error (1292): Incorrect date value: '0000-00-00' for column `test`.`d` at row 1

      As you can see this is totally wrong, there is no such value 0000-00-00 in this table, and the alter statement should succeed.

            but error on 10.3-10.5
