--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> ---
The problem seems to exist in gcc 4.7.3 and within the recent 4.9.0 trunk. The
following variant of the code removes unnecessary library dependencies and
constexpr (which is not needed to reproduce the problem):

//----------------------------------
template <typename T>
struct foo
{
};

template <int N, typename T, typename ...Us>
bool bar(T &&, Us &&...)
{
    return false;
}

template <int N, typename T, typename ...Us>
bool bar(foo<T> &&, Us &&...)
{
    return true;
}

int main()
{
    bar<0>(foo<int>(), 1, 2);
}
//----------------------------------
