+------- Additional Comments From ginga@kit.hi-ho.ne.jp  2003-10-13 03:37 -------
+I fixed this problem, but in the next stage I encountered another bug 
+(maybe) in SlashIterator.
+
+XmlDocument doc = new XmlDocument ();
+doc.LoadXml 
+("<root><foo/><bar/><bar/><foo/><baz/><bar/><foo/></root>");
+XPathNavigator nav = doc.CreateNavigator ();
+
+//(1) runs well with my fix
+//XPathNodeIterator iter = nav.Select ("/root/bar|/root/foo");
+//(2) incorrectly outputs extraneous bar * 3
+XPathNodeIterator iter = nav.Select ("//bar|/root/foo");
+//(3) results in infinite loop(!)
+//XPathNodeIterator iter = nav.Select ("//bar|//foo");
+
+while (iter.MoveNext ())
+	Console.WriteLine ("Name: " + iter.Current.Name);
+
+It would be better we apply the patch after fixing this problem.
