Subject: [OMPI users] Bus Error in ompi_free_list_grow
From: Geraldo Veiga (gveiga+openmpi_at_[hidden])

Hi to all,

I am using the same subject of a recent message I found in the list archives
of this mailing list:

http://www.open-mpi.org/community/lists/users/2008/10/7025.php

There was no follow-up on that one, but will add this similar report in
case a list member can give us an idea of how to correct it. Or whose bug
this could be.

My application behaves as expected when I run it in a single host and
multiple MPI nodes of our SGI Altix ICE 8200 cluster with in
InfiniBand. When I try the same with multiple hosts, using the PBS batch
system the program terminates with a segmentation fault:

Most of the software infrastructure is provided by the Intel propack.  Any
hints of where to look further into this bug?
Thanks in advance.
