[Bug c++/35546] New: __attribute__(format...) broken for membes of template classes?

["duz at sol-3 dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Source code (no includes needed, no preprocessor involved at all)
------------------------------------------------------------------------
template <int N>
class T
{
  void operator() (char const * ...) __attribute__((format(printf,2,3)));
};

template class T<3>;
------------------------------------------------------------------------

This compiles fine with many different gcc versions up to
including gcc-4.2.2 and does not compile with gcc-4.3.
Error messages and details of compiler below.
