["s__nakayama at infoseek dot jp" <gcc-bugzilla at gcc dot gnu dot org>]

test case

template<class T> struct B
{
  void foo(T) {}
};

template<class T> struct D: B<int>, B<double>
{ 
  using B<int>::foo;
  using B<double>::foo;
  void bar() { foo(3); }
};

int main()
{
  D<int> x;
  x.bar();
  return 0;
}

$g++ cc.cpp
