Hmm... the error seems to be triggered by this line of code:
libMesh::err << "node " << (*nodej)->id() << ", " <<
*(Point *)(*nodej) << " has HilbertIndices " <<
node_keys[j] << std::endl;
I don't really understand what this is doing at a glance. Roy, is that a
C-style cast to a Point *, then a dereferencing?
Xujun, if you comment out lines 615-619 in
mesh_communication_global_indices.C, does the error go away? That's a
better solution than commenting out a line in ostream_proxy.h...
