Subject: [OMPI devel] Silly question

I know that it should be uncommon but why I get an error while I try to run a "parallel" application with only one process?

aopclf:ping fialho$ mpirun -np 1 ./ping
[Fialho-2.local:02834] OPAL dss:unpack: got type 32 when expecting type 9
[Fialho-2.local:02834] [[57446,1],0] ORTE_ERROR_LOG: Pack data mismatch in file ../../../../orte/mca/grpcomm/base/grpcomm_base_modex.c at line 330
[Fialho-2.local:02834] [[57446,1],0] ORTE_ERROR_LOG: Pack data mismatch in file ../../../../../orte/mca/grpcomm/bad/grpcomm_bad_module.c at line 444
aopclf:ping fialho$

I understand the error and I know the reason, but this is a limitation from Open MPI (due to modex?) or from the MPI standard?
