--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> ---
This looks like a more fundamental name lookup problem of gcc to me. It can be
reproduced with function object types that are no lambda closures:

template <class... Fs> 
struct overload_set : Fs...
{
  overload_set(Fs... f)
    : Fs(f)...
  {}  
};

template <class... Fs> 
overload_set<Fs...> overload(Fs... x)
{
  return overload_set<Fs...>(x...);
}

template<class T>
struct Closure 
{
  void operator()(T) const {}
  using FPtr = void(*)(T);
  operator FPtr() const;
};

int main()
{
  double d = 10; 
  overload(
      Closure<int>(),
      Closure<double>(),
      Closure<char>() 
    )(d);
}

Thanks Daniel. Could even be a duplicate then.
