Maybe this isn't the bug you're looking for but you shouldn't be using ff1x multicast addresses in a test like this; ff1x means that the multicast group is of "interface-local scope" and it isn't useful for multicast forwarding. So the kernel might be correct in not installing multicast forwarding state for a group address like this (but if it's a conscious decision, maybe the failure mode should be better). See S 2.7 of RFC4291.
