Hello, 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 child.c (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. Regards,
information.tgz
