Just if wondering what the actual code is, here's the bit causing the trouble:
AOApplicationToPetsc(ao, ghostNodes.size(), (int*)ghostNodes); VecCreateGhost(comm, localNodes.size(), PETSC_DECIDE, ghostNodes.size(), (int*)ghostNodes, &v); AOPetscToApplication(ao, ghostNodes.size(), (int*)ghostNodes); when the code is in serial, ghostNodes.size() = 0 and (int*)ghostNodes = NULL.
