Node Symlinks allows creating duplicate menu links with unique id to all nodes. As a result all these duplicates have unique menu trails and breadcrumbs.

Code

function nodesymlinks_get_breadcrumbs() {
  $crumbs = array();
  if (variable_get('nodesymlinks_crumbs_include_home', 1)) {
    $crumbs[] = l(t('Home'), '<front>');
  }
  $trail = _nodesymlinks_menu_get_active_trail();
  $depth = count($trail) - 1;
  for ($i = 0; $i < $depth; ++$i) {
    $crumbs[] = l($trail[$i]['title'], $trail[$i]['href']);
  }

  // Add current item as last crumb if display type is set so.
  $last_crumb_type = variable_get('nodesymlinks_crumbs_lastcrumb', 'parent');
  if ($last_crumb_type == 'current_plain') {
    $crumbs[] = $trail[$depth]['title'];
  }
  elseif ($last_crumb_type == 'current_link') {
    $crumbs[] = l($trail[$depth]['title'], $trail[$depth]['href']);
  }
  return $crumbs;
}
