Problems with the unexpected behavior of vshufpd

Hello there.

I wrote this little piece of code:
#include <immintrin.h>
#include <stdio.h>

typedef struct quaternion {
    double a;
    double i;
    double j;
    double k;
} quaternion;

int main(void) {
    struct quaternion n1 = (struct quaternion){3.141592, -2.72192, -6.28384, -9.478};

    __m256d n1_t = *(__m256d *)&n1;

                            // 0b00011011
    n1_t = _mm256_shuffle_pd(n1_t, n1_t, _MM_SHUFFLE(0,1,2,3));
    *(__m256d *)&n1 = n1_t;

    printf("\t%lf %lf %lf %lf\n", n1.a, n1.i, n1.j, n1.k);

    return 0;
}
P.S. Explanation of what should be in place a mask I have not found, so as to use SSE* way.

I expected see this result: 3.141592 -2.721920 -6.283840 -9.478000

But i got this: -2.721920 -2.721920 -6.283840 -9.478000

I have only two possible reasons:
1) The mask is defined in another way
2) Error in Intel® Software Development Emulator
