When I compile version 2.3.5, I get this warning message:
In file included from tools/topo/hwloc/topo_hwloc.c:8:0:

    inlined from ‘HYDT_topo_hwloc_init’ at

When subsequently I try running a simple send/receive test, I get
segmentation faults in MPI_Send and MPI_Recv, either
  libmpi.so.12 MPIDI_CH3_Rendezvous_rget_recv_finish
  libmpi.so.12 MRAILI_RDMA_Get_finish
  libmpi.so.12 MRAILI_Process_send
  libmpi.so.12
  libmpi.so.12 MPIDI_CH3I_MRAILI_Cq_poll_ib
  libmpi.so.12 MPIDI_CH3I_read_progress
  libmpi.so.12 MPIDI_CH3I_Progress
  libmpi.so.12 MPI_Recv
or
  libmpi.so.12 MPIDI_CH3_Rendezvous_rget_send_finish
  libmpi.so.12 handle_read
  libmpi.so.12 MPIDI_CH3I_Progress
  libmpi.so.12 MPI_Send

This version was configured using the same options as my 2.3.4
installation, namely,
    --prefix="${INSTALL}"
    --enable-fast=O3,ndebug
    --enable-shared
    --with-pic
    --disable-fortran
    --disable-cxx
    --disable-mcast
    --enable-threads=multiple
    --enable-error-messages=all
    --with-pm=hydra
