--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> ---
Removing library dependencies and simplifying a bit (The problem seems not
related to contexpr, for example):

template<class E, E V, int CNT>
struct seq_t
{
     template<E... Es> struct seq{};

     template<int N, E... Es>
     struct gen : gen<N - 1, V, Es...>{};

     template<E... Es>
     struct gen<0, Es...> : seq<Es...>{};

     struct bits_t{ E e[CNT]; };

     template<E... Es>
     static bits_t init(seq<Es...>) {return {{Es...}};}

     static bits_t init() {return init(gen<CNT>{});}
};

typedef seq_t<int, 123, 5> wow;

int main()
{
  wow::init();
}
