--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
So AFAIU

int main(int argc, char *argv[]) {
    uint8_t raw[] = { 0xaa, 0xbb, 0xcc, 0xdd, 0x11, 0x22 };
    SS instance;
    memcpy (&instance, raw, sizeof (SS));
    printf("%x, %x\n", instance.a, instance.b);
    return 0;
}

would be OK(?)
