Reading on the web, I think I understand what the issue is, but have some
trouble understanding why you see it and I don?t when surely it's the same
Intel target (but different OS)?
The workaround might be to pass stdarg instead of "...". I won't be able to
reproduce it here so perhaps I will commit a fix and then you can test?

With sufficient thrust, pigs fly just fine. However, this is
not necessarily a good idea. It is hard to be sure where they
are going to land, and it could be dangerous sitting under them
as they fly overhead. -- RFC 1925
