Hi, Is there an internal check to see if the 'ghost' pointer in VecCreateGhost() is NULL ? This can happen, for example, if the code is run in serial and the there are no ghost points (hence n_ghost = 0 and ghost = NULL(implementation dependent of course) ). AOXXXXToYYYY functions seem to crash if the corresponding pointer is NULL.
