Hi,

I'm not providing any help but FWIW, I got the same problem with
trunk and OpenMpi 1.3.2 on Linux ubuntu 9.04.
I also noticed a problem with all_reduce when in_values == out_values,
openmpi 1.3.2 detect that MPI_IN_PLACE should be use. I diid not have
that one with previous versions of OpenMpi, maybe that release detects
more issues than the previous ?

Regards,
