--- Comment #4 from Philipp <carlphilippreh at gmail dot com> ---
Thank you for providing a fix for the test case so quickly. However, the issue
resurfaces in a slightly more involved example using a variadic lambda, which I
tested using gcc-6-20160221. Again, this code is accepted by gcc-5.3 and clang. 


#include <type_traits>
#include <utility>

template<typename T>
void sink(T &&)
{
        static_assert(std::is_same<int,T>::value,"");
}

int main()
{
        auto const g([](auto &&...  _var) {
                sink(std::forward<decltype(_var)>(_var)...);
        });

        g(0);
}
