I am not actually sure if this is UB, and anyway for FFI shims, Miri currently does not attempt to distinguish between arguments passed via variadics vs directly. So let's be consistent.
(Programs that ran into this error will anyway immediately fall through to the "unsupported" message on the next line.)
