class A[+T] {
  protected[this] def f(t: T) { }
}
class B extends A[Any] {
  f()
}

Doesn't work if compiled together: covariant type T occurs in contravariant position in type T of value t. Works if call to f in B is omitted.

This appears to have been fixed - the sample compiles without complaint.
