Same thing it mens in any Squid version.

* The object at the given URL uses Vary header feature of HTTP.
  - Squid indexes the cache store by URL, so do deal with such features we place a special "vary object marker" in the cache at the index where URL lookup can find it. That object indicates that Vary is used by this resource and what Vary: header key is to be used. Squid then must perform a second cache lookup with the new key to find an object relevant for the current client. The object found by the second lookup is expected to be the real response.

* In your case the second lookup discovered a loop back to the same or another vary object.
  - Squid is just warning you that the cache is corrupted by that loop and will fetch a new object from the network.
