I have built the release candidate for ga-4.1 with OpenMPI 1.2.3 and

Running the test.x for 3 Myrinet nodes each with 4 cores I get the
following error messages:

[0,1,3]: OpenIB on host node057 was unable to find any HCAs.
Another transport will be used instead, although this may result in
lower performance.

FWIW, this specific warning is fixed in the upcoming v1.3 series (I
assume you built on a machine with libibverbs installed, but no
OpenFabrics-capable devices).
IIRC, you can manually disable this warning by telling Open MPI to
avoid the openib BTL (I can't test the v1.2 series on a linux machine
ATM to verify this):
mpirun --mca btl ^openib ...
ARMCI configured for 3 cluster nodes. Network protocol is 'MPI-SPAWN'.

It looks like ARMCI is seg faulting...? Beyond that, Bad Things will
happen at the MPI layer before it aborts.
I'm unfamiliar with "ga" or ARMCI, so I don't know exactly what's
happening here...
