Subject: [OMPI users] A problem with running a 32-bit program on a 64-bit machine
From: Avinash Malik (amalik_at_[hidden])

        I have compiled openmpi-1.5.1 as a 32-bit binary on a 64-bit
        architecture. I have a problem using MPI_Comm_spawn and
        MPI_Comm_spawn_multiple, when MPI_Info is used as a non NULL
        (MPI_INFO_NULL) parameter. I get a segmentation fault. I have
        the exact same code running fine on a 32-bit machine. I cannot
        use the 64-bit openmpi due to problems with other software,
        which uses openmpi, but can only be compiled in the 32-bit mode.

        I am attaching all the information, in a .tgz file. The .tgz
        file consists of:
        (1) The c-code for a small example two files parent.c and
        (2) The compile_command that I ran on a 64-bit machine.
        (3) The run command to run the system
       compiling openmpi-1.5.1.
        (4) ompi_info_all
        (5) The error that I get, it's a segmentation fault.
