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
(5) The error that I get, it's a segmentation fault.
