      The failure was hit under below code context in test/csuite/random_directio/main.c:

      check_db()
      {
          ...
              printf("starting full scan at %" PRIu64 "\n", id);
              gen_kv(keybuf, kvsize, id, 0, large_arr[0], true);
              cursor->set_key(cursor, keybuf);
              testutil_check(cursor->search(cursor));   // failed here
              th = 0;
          ...
      }
