Fails for me with 1.4.3 with gcc, but works with intel; works with 1.4.4
with gcc or intel; fails with 1.5.5 with either. Succeeds with intelmpi.
On the other hand, it works everywhere if I pad the rcounts array with
an extra valid value (0 or 1, or for that matter 783), or replace the
allgatherv with an allgather.
