sorry... here is a the complete trace:

so i'm still not sure if i've built this correctly to begin with, since
the crash is caused in mpich-master-3.0.3/src/pmi/pmi2/simple2pmi.c
so not sure if that should be using slurm's pmi2 plugin or if this is
potentially an issue i should enquire about on the mpich forum ?
this is my code:
#include "mpi.h"
#include <iostream>
int main(int argc, char *argv[])
{
MPI_Init(&argc, &argv);
int rank,c_size;
MPI_Comm_size( MPI_COMM_WORLD, &c_size );
MPI_Comm_rank( MPI_COMM_WORLD, &rank );
std::cerr << "Hello World from rank " << rank << " / " << c_size <<
std::endl;
MPI_Finalize();
}
with LF -lpthread -lmpich
Kind Regards,
Christoph
