The last sentence is wrong: this bug is common to all versions.
The fix is simple enough, and is already in CVS.
You just have to replace the definition of hide_private_methods in
typing/ctype.ml by
let hide_private_methods ty =
match (repr ty).desc with
Tobject (fi, nm) ->
nm := None;
let (fl, _) = flatten_fields fi in
List.iter
(function (_, k, _) ->
match field_kind_repr k with
Fvar r -> set_kind r Fabsent
| _ -> ())
fl
| _ ->
assert false
