BKE_id_material_eval_ensure_default_slot(&mesh->id);

could be replaced with

  if (mesh) {
    BKE_id_material_eval_ensure_default_slot(&mesh->id);
  }

in node_geo_mesh_primitive_line.cc. But not sure if that really is the problem. Maybe a node connected in the wrong slot shouldn't trigger this at all. (but MSVC does warn that the code is dereferencing a null pointer)
