It appears to be this one.

I'll return what I've gathered so far to th
That's understandable - if you don't disable xml2, then hwloc uses the xml2
library to do the topology encoding. We rely on their internal "quasi-xml"
encoding method, which I believe provides some different data (and definitely
different format). I suspect this is causing the confusion, though

What I find very interesting is that the hwloc configure options
--disable-cairo --disable-libxml2 turn the bug off.
I'll keep walking through the execution in gdb maybe I'll
Yeah, it's failing when trying to unpack the topology obtained from hwloc. My
guess is that one of the following calls changed in hwloc-1.4.3:

rc = OPAL_ERROR;
free(xmlbuffer);

I don't know if Fedora RPMs include -g in their builds, or if Fedora includes a
debuginfo RPM that you could install such that you can attach a debugger and be
able to dig into OMPI's internals yourself.
If that doesn't work, you might need to build from source yourself, link

The fedora package comes with a debuginfo package that has everything

I see - I didn't look at the redhat bug list. Sadly, I have no idea how to
debug it. The Fedora package is built optimized, so no OMPI debugging output is
available and a debugger won't tell us a lot.
Best guess is that there is something in the build that doesn't match the
user's system. The n

Ah! That would indicate an issue with the external hwloc package they provided,
which is the big reason we don't recommend installing from packages. We have
internal copies of hwloc and libevent that ensure (a) they are at the proper
level, and (b) they are configured properly for OMPI's use.

So I built openmpi-1.6.5 from the tar ball and of course
everything works fine well my simple program got through
Mpi_init and printed its rank.

Afraid I have no earthly idea of the problem - you might try taking it up with

So now the fun part for me is to try and find it or in failing to

Not offhand. The error you're seeing *typically* indicates that you've got a
mismatch of OMPI version somewhere. Are you running on multiple machines with
different Open MPI versions, perchance?
If you're running only on a single machine, try completely uninstalling the

No, I'm sure I'm using a different version of Open MPI in Fedora
18 from the one I was using in Fedora 17.
I have only the Open MPI provided by the Fedora distribution.

Are you sure you're using the same version of OMPI on this new OS? They
typically distribute one in your default path, so I'd check to ensure that you
really are using the version you think.

I just upgraded the OS on one of my workstations from Fedora 17 to 18
and now I can't run even the simplest MPI programs.
I filed a bug report with Fedora's bug tracker :

My simple program is attached as mpi_simple.c
