It might be that we haven't been testing this function enough, so a bug like this is not unlikely. > The violated condition was: > owned_elements.size()==size() > Additional information: > The locally owned elements have not been properly initialized! > This happens for example if this object has been initialized with exactly > one overlapping IndexSet. Can you try initializing your ghosted vector with vec.reinit(locally_owned_index_set, locally_relevant_index_set, mpi_com); instead of only specifying the ghosted set?

I was hoping to have an implementation for that soon (we did some progress towards it last month).

One workaround for now might be to switch to a shared::Triangulation.
