Just to be sure: you compiled your test MPI application with -g, right?

No, both of those should be just for OMPI developers; you should not
need them for user installations. Indeed, OMPI should build itself
with -g as relevant for TV support (i.e., use -g to compile the
relevant .c files in libmpi); you shouldn't need to build OMPI itself
with -g.
