Bug#1111125: pmix: Makes openmpi crash on startup

[Samuel Thibault]

Source: pmix
Version: 6.0.0-2
Severity: grave
Justification: renders package unusable

Hello,

Since the newer pmix upload, openmpi programs just crash:

#include <mpi.h>
#include <stdio.h>

int main(int argc, char *argv[]) {
	int comm_rank = -1;
	int comm_size = -1;
	MPI_Init(&argc, &argv);
	MPI_Comm_size(MPI_COMM_WORLD, &comm_size);
	MPI_Comm_rank(MPI_COMM_WORLD, &comm_rank);
	fprintf(stdout, "My rank is %d/%d\n", comm_rank, comm_size);
	MPI_Finalize();
}

$ mpicc.openmpi  test.c -o test
$ mpirun.openmpi -np 2 ./test
Segmentation fault
