Quoting Juergen Rose <r...@rz.uni-potsdam.de>:
Hi,
I was just able to install the patched Rmpi on the second system with
openmpi-1.5.3. What can we that Rmpi_0.5-9a.tar.gz becomes a standard
CRAN package?
Regards Juergen
Now there is a new problem. Testing openmpi-1.5.3-r1 and
Rmpi_0.5-9a.tar.gz with the attached R script I got a Segmentation
fault or the program hangs in the vicinity of closeCluster() and
mpi.quit(), which does not happen with openmpi-1.4.3 and
Rmpi_0.5-9.tar.gz:

It seems, that the issue is not a special Rmpi problem, compare
