Code

function _drupal_shutdown_function() {
  $callbacks =& drupal_register_shutdown_function();

  // Set the CWD to DRUPAL_ROOT as it is not guaranteed to be the same as it
  // was in the normal context of execution.
  chdir(DRUPAL_ROOT);
  try {
    reset($callbacks);

    // Do not use foreach() here because it is possible that the callback will
    // add to the $callbacks array via drupal_register_shutdown_function().
