This is fixed in trunk. I'm adding the testcase and removing the regression
marker.

--- Comment #1 from Alexandre Oliva  ---
The reason private works where protected doesn't is that private access
checking uses is_friend, whereas protected access checking uses
friend_accessible_p.  The latter is supposed to grant access whenever is_friend
would (that's the assert that fails), but while is_friend checks various
possibilities of template specialization with is_specialization_of_friend,
friend_accessible_p seems to only handle one layer of template friends.

I'm afraid I don't quite see how to extend e.g. protected_accessible_p, used by
friend_accessible_p, to deal with additional template layers.
