I do not know the exact problem: the description I received was something
like "it works on linux, but not on windows". And I never had any way to
check (no windows here... And wine was unable to reproduce any problem,
probably because it is based on linux).

Anyway, my patch was here:
http://roundup.mplayerhq.hu/roundup/ffmpeg/msg2210
(not identical to this patch, but similar - I think it has the same effect),
and you can find more details here:
http://roundup.mplayerhq.hu/roundup/ffmpeg/issue481

The discussion continued talking about the order of multicast join and bind,
and I produced a new patch:
http://roundup.mplayerhq.hu/roundup/ffmpeg/msg2250
but it seems that there was no useful conclusion. You have windows skills,
so I guess you can understand what's going on, and propose a correct fix ;-)
