That's probably a shortcoming in vectorization_logic itself. Perhaps that

We figured out the error in IRC, it was a missing HasDiv=1 in
packet_traits<float>. As I don't have an Altivec available to test it,
I'm waiting for Konstantinos to push that change.
My change actually exposes that integer vectorization with AVX is
somewhat undefined. We provide Packet8i but don't implement
vectorization, since it's only available with AVX2:
