      Description

      CREATE TABLE t (a INT, b INT);
      INSERT INTO t VALUES (1,1),(2,2);
      CREATE ALGORITHM=MERGE VIEW view1 AS SELECT MAX(a) as f FROM t;
      --delimiter $
      CREATE PROCEDURE sp()
      BEGIN
        SELECT * FROM view1;
        SELECT * FROM x;
      END $
      --delimiter ;
       
      --error ER_NO_SUCH_TABLE
      CALL sp;
      ALTER TABLE t DROP a;
      CALL sp;
       
      # Cleanup
      DROP PROCEDURE sp;
      DROP VIEW view1;
      DROP TABLE t;
      

      If it doesn't fail right away, please try an ASAN build.
