in many cases there are more blocks than ranks. ex AMR and Estelle's use case. she has 1 sender rank and wants to use many receiver ranks. Greg said that this is a "feature" of flexpath where they need to use a vector instead of a pointer. it may be an easy fix, and will affect adios 2 as well.

below we have 4 blocks with 1 sender and 2 receivers. this is from our regression tests, and can be used to reproduce.
