Heap-buffer-overflow in MPI_Init

Hello,

I'm compiling this example:

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

int main(int argc, char** argv) {
    MPI_Init(NULL, NULL);
    MPI_Finalize();
}

And I get the following memory error. Is this a false positive? Could this be fixed if not?

$  mpicxx -show && mpicxx hello.cpp -fsanitize=address && mpirun -np 1 ./a.out

For reference, here is what I get with MPICH:

$ mpicxx.mpich hello.cpp -fsanitize=address && mpirun.mpich -np 1 ./a.out && echo $?
0

Thank you for your help.
