There are several low level updates coming to Indigo with patches recently merged in catkin, ros_comm, and releases pending for class_loader, pluginlib, common_msgs, and eigen_stl_containers. https://github.com/ros/rosdistro/pulls
As such I'd like to get the current set of updates synced, before we do the large rebuild so we can have time before a sync for testing the low level updates. As such I'm going to suggest attempting to resolve the cob_* issues and make a release by Wednesday next week.
If anyone knows of anything relevant that's not above please reply.
