Hi,

I've reported the following issue:
https://github.com/xtensor-stack/xsimd/issues/386

I am not sure if the issue comes from clang-cl or the xsimd itself but, it only
fails on Windows using clang-cl.

It works well with clang on OSX and Linux, and while looking at the code I've
seen nothing wrong with the code itself, yet the generated assembly seemed
wrong.

Regards,
Alexandre
