    Description

      SET sql_mode='';
      		 
      DELIMITER $$
      		 
      BEGIN NOT ATOMIC
      		 
        DECLARE a INT;
      		 
        SET a=(SELECT 1 FROM DUAL UNION SELECT HIGH_PRIORITY 2 FROM DUAL);
      		 
      END;
      		 
      $$
      		 
      DELIMITER ;


      ERROR 2013 (HY000): Lost connection to MySQL server during query

      Note, 10.3 correctly returns the expected error without crashing:

      ERROR 1234 (42000): Incorrect usage/placement of 'HIGH_PRIORITY'
