I think I see the problem. Please try the following patch in addition
to the previous one:
diff --git a/lib/mcast-snooping.c b/lib/mcast-snooping.c
index 7fd0b9a..f71321d 100644
--- a/lib/mcast-snooping.c
+++ b/lib/mcast-snooping.c

b = xmalloc(sizeof *b);
ovs_list_init(&b->bundle_node);

}
b->expires = time_now() + idle_time;
Thanks,
Ben.
