+Summary: Exception attempting to join IPv6 multicast group
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+When attempting to join an IPv6 multicast group the following exception is
+thrown:
+
+Unhandled Exception: System.Net.Sockets.SocketException: Invalid arguments
+  at System.Net.Sockets.Socket.SetSocketOption (SocketOptionLevel level,
+SocketOptionName name, System.Object opt_value) [0x00000] 
+  at mcast.Main (System.String[] args) [0x00000] 
+
+The strace output reads as follows:
+
+bind(7, {sa_family=AF_INET6, sin6_port=htons(12345), inet_pton(AF_INET6,
+"::", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0
+setsockopt(7, SOL_IPV6, IPV6_ADD_MEMBERSHIP,
+"\0\0\0\0\0\0\0\0\30\314\7\0\0\0\0\0", 16) = -1 EINVAL (Invalid argument)
+
+Please find a testcase attached. Similar bugs have been filed earlier
+(#80593 for example), mostly regarding architecture issues. This time it
+works well for IPv4 addresses but fails for IPv6.
+
+The most current Linux Installer for x86 from www.mono-project.org produced
+the same output. Under MS .NET 3.0, however, the testcase executes without
+errors.
+
+Steps to reproduce the problem:
+1. Create a new IPv6 socket
+2. Bind the socket
+3. Subscribe to the IPv6 mcast group
+
+Actual Results:
+Exception
+
+Expected Results:
+Wait until some data are received then exit.
+
+How often does this happen? 
+Always
