Ok. These failures look extremely odd.

2: Abort(33616) on node 0: Fatal error in internal_Comm_size: Invalid
communicator, error stack:
2: internal_Comm_size(30769): MPI_Comm_size(comm=0xb6061990,
size=0xb86caa54) failed
2: internal_Comm_size(30723): Invalid communicator
The program has basically only called
int comm_size = -1;
MPI_Init(, );
MPI_Comm_size(MPI_COMM_WORLD, _size);
Which is essentially a smoketest for a working mpi implementation.
And these error messages are coming from mpich, not from openmpi!
I'm wondering if ubuntu is perhaps mixing libmpi from mpich and from
openmpi?

Done so in the git tree. I have also added a smoketest for working MPI
implementations (without any use of eztrace).
