[OMPI users] [openib] segfault when using openib btl

Hi,
I'm observing a random segmentation fault during an internode parallel
computation involving the openib btl and OpenMPI-1.4.2 (the same issue
can be observed with OpenMPI-1.3.3).
mpirun (Open MPI) 1.4.2

If I choose not to use the openib btl (by using --mca btl self,sm,tcp
on the command line, for instance), I don't encounter any problem and
the parallel computation runs flawlessly.
I would like to get some help to be able:
- to diagnose the issue I'm facing with the openib btl
- understand why this issue is observed only when using the openib btl
and not when using self,sm,tcp
Any help would be very much appreciated.
The outputs of ompi_info and the configure scripts of OpenMPI are
enclosed to this email, and some information on the infiniband drivers
as well.
Here is the command line used when launching a parallel computation
using infiniband:
path_to_openmpi/bin/mpirun -np $NPROCESS --hostfile host.list --mca
btl openib,sm,self,tcp --display-map --verbose --version --mca
mpi_warn_on_fork 0 --mca btl_openib_want_fork_support 0 [...]
and the command line used if not using infiniband:
path_to_openmpi/bin/mpirun -np
$NPROCESS
--hostfile host.list --mca btl self,sm,tcp --display-map
--verbose --version --mca mpi_warn_on_fork 0 --mca
btl_openib_want_fork_support 0 [...]
Thanks,
Eloi
