          Adding new columns to an already initialized column crashes:

          how to repeat:

          static int test_mdev_4994(MYSQL *mysql)
{
  DYNAMIC_COLUMN dyncol;
  uint key= 1;
  DYNAMIC_COLUMN_VALUE val;
  int rc;

  mariadb_dyncol_init(&dyncol); /* see patch for MDEV-4993 */
  rc= mariadb_dyncol_create_many_named(&dyncol, 1,&key, &val, 0);  /* crash */
  FAIL_IF(rc < 0, "Unexpected error");
  return OK;
