I'll try.

"Address not mapped" means that the program tried to access a memory
location that is not part of the process' address space (e.g. null
pointer).

What follows is a backtrace of the functions currently being executed
(in reverse order, as found on the stack). I'd hazard a guess that
it's not OMPI's fault but VASP's, since the segfault happens in one of
its functions. Maybe you should have a look there.
