For the following code:

/**
 * Class Related
 */
class Related {
  /**
   * A related static function.
   */
  static const Related& local() const;
};


/**
 * Class Test
 */
class Test {
  /**
   * @deprecated Deprecated function.
   */
  void func(const Related& r = Related::local());
};

When generating the deprecated page, the following warning is produced:

Generating docs for page deprecated...
deprecated:1: warning: explicit link request to 'local()' could not be resolved

It appears it is attempting to produce a link for 'Related::local', however since that function is documented it doesn't seem like it should be an issue.

This issue may be related to 627967, however the workaround described there doesn't seem to apply.
