--------------------------------------------------------------------------
mpirun noticed that process rank 1 with PID 7241 on node Gambit-3.local exited on signal 6 (Abort trap).

========================================================

Lines 484 - 486 of dolfin/main/MPI.cpp are:

dolfin::uint dolfin::MPI::index_owner(uint index, uint N)
{
  assert(index < N);
  ......

I can't see why this assertion fails.
