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 nidmap_init routine unpacks a buffer that contains a bunch of process mapping info that mpirun packed into it - don't usually see an error in there.
