      Description

      This script crashes the server:

      CREATE TABLE IF NOT EXISTS t1 (i INT);
      DROP FUNCTION IF EXISTS f1;
      DELIMITER $$
      CREATE FUNCTION f1() RETURNS VARCHAR(16383)
      BEGIN
        RETURN 'test';
      END;
      $$
      DELIMITER ;
      CREATE OR REPLACE TABLE t1 AS SELECT f1();
      

      Note, if I replace CREATE OR REPLACE to a DROP followed by CREATE, it works fine:

      CREATE TABLE IF NOT EXISTS t1 (i INT);
      DROP FUNCTION IF EXISTS f1;
      DELIMITER $$
      CREATE FUNCTION f1() RETURNS VARCHAR(16383)
      BEGIN
        RETURN 'test';
      END;
      $$
      DELIMITER ;
      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 AS SELECT f1();
