    Description

      It should be related to MDEV-30730, but that one has some dependency on Galera and (probably because of that) affected versions are different.

      CREATE TABLE t (f DOUBLE NOT NULL, vf DOUBLE AS (RAND(1 AND f)) VIRTUAL);
      ALTER TABLE t MODIFY COLUMN IF EXISTS x INT;
      INSERT INTO t (f) SELECT f FROM t;
       
      # Cleanup
      DROP TABLE t;
