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 
#include 

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

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

g(0);
}

At least using g++ 5.3 preprocessed sources, this is rejected since r229210.
