Background information
What version of Open MPI are you using? (e.g., v4.1.6, v5.0.1, git branch name and hash, etc.)
OpenMPI v5.0.5
Describe how Open MPI was installed (e.g., from a source/distribution tarball, from a git clone, from an operating system distribution package, etc.)
Installed using Spack
Please describe the system on which you are running
- Operating system/version: Pop!_OS 22.04 LTS
- Computer hardware: 12th Gen Intel(R) Core(TM) i7-1255U
- Network type: none
Details of the problem
The following program:
#include <mpi.h>
int
main(int argc, char** argv) {
MPI_Info info;
MPI_Info_create(&info);
MPI_Session s1, s2;
MPI_Session_init(MPI_INFO_NULL, MPI_ERRORS_RETURN, &s1);
MPI_Session_finalize(&s1);
MPI_Session_init(MPI_INFO_NULL, MPI_ERRORS_RETURN, &s2);
MPI_Session_finalize(&s2);
}fails at runtime, as follows:
$ mpirun -np 1 src/Test

Removing either the call to MPI_Info_create() or the second call to MPI_Session_finalize() allows the program to complete. Another workaround I've found is to add a call to MPI_Init() prior to the call to MPI_Info_create().
