I've seen some failures on arm and s390x hosts after enabling host vector support. It turns out that the malloc for these hosts does not provide 16-byte alignment.
We already have a function that can alloc with alignment, but we need to pass this down from the structure. We also don't want to use this function unconditionally, because the windows version does page allocation, which would be overkill for the vast majority of the objects allocated. r~ Cc: Paolo Bonzini <pbonz...@redhat.com> Cc: "Daniel P.
