It appears the problem was not with the command line parser but the rsh plm. I don't know why this problem was not occuring before the command line parser changes but it appears to be resolved now. This commit was SVN r27527. The following SVN revision numbers were found above: r27451 --> open-mpi/ompi@d59034e6ef r27456 --> open-mpi/ompi@ecdbf34937
