Poniższy kod:

#include <iostream>
#include <array>
using namespace std;

constexpr int N = 1000000;
constexpr int f(int x) { return x*2; }

typedef array<int, N> A;

template<int... i> struct F { static constexpr A f() { return A{{ ::f(i)... }}; } };

template<class A, class B> struct C {};
template<int... i, int... j> struct C<F<i...>, F<j...>> : F<i..., (sizeof...(i)+j)...>
{
        using T = F<i..., (sizeof...(i)+j)...>;
};

template<int n> struct S : C<typename S<n/2>::T, typename S<n-n/2>::T> {};
template<> struct S<1> : F<0> { using T = F<0>; };

constexpr auto X = S<N>::f();

int main()
{
        cout << X[3] << endl;
}

Tworzy wewnętrzny błąd kompilatora w GCC 4.7 w-std=gnu++11 tryb.

$ g++ -std=gnu++11 test.cpp
g++-4.7.real: internal compiler error: Killed (program cc1plus)

Co jest nie tak?
