Oh, good to see you're doing the move! Don't hesitate to cc me and Dylan on any
meson issue you have.

Good comparison point, I forgot to ask that.

So that really is the issue :/

Yes indeed, it sounds like a reasonable candidate for this issue.
You can try disabling it with `meson configure -D power8=false`.

I'll try to have a closer look tomorrow so see if `-mpower8-vector` is meant to
work with C++ or not.
