These are link-local addresses ala rfc3927. That must be the issue. The kernel doesn't bind to the given interface. It doesn't return an error but rather selects some other random interface?! Sounds like a kernel bug, or maybe there is some sysctl (rp_filter?) that allows multicast on link-local interfaces. Maybe that is also the issue with IPv6 link local addresses that I have seen...
