Segmentation fault when running an MPI job on MacOS Monterey with the M1 chip

[ktbolt]

I have successfully built svSolver on MacOS Monterey / M1 chip using OpenMPI and a local VTK install.

I can run simulations fine on a single processor but when I try to run using multiple processors I get a Segmentation fault in Metis

Signal: Segmentation fault: 11 (11)

It seems that the problem occurs in the function void GKfree(void **ptr1, ...) that frees memory using a variable argument list. The seg fault occurs when processing arguments

  while ((ptr = va_arg(plist, void **)) != LTERM) {
    if (*ptr != NULL) {
      free(*ptr);
    }
   *ptr = NULL;
  }

The first call to va_arg(plist, void **) returns a bad memory address.

If I modify GKfree() to just return then the simulation runs fine.
