Just to be sure: you compiled your test MPI application with -g, right?
Does openmpi need to be built with either --enable-debug or --enable-mem-debug? The "configure --help" says the former is not for general MPI users. Unclear about the latter.
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.
