And here's the definite answer from a clang developer:

  The rule for determining when a base class function declaration
  introduced by a using-declaration is hidden by a derived class
  function declaration does not take the template parameter list into
  account: http://eel.is/c++draft/namespace.udecl#15.sentence-1

  So clang's behaviour is conforming and gcc's behaviour is not. At
  the very least, though, we should issue a warning for the using
  declaration, because this is a surprising rule.
