+Summary: Custom XPath Functions sample from CodeProject crashes
+Custom XPath Functions sample from CodeProejct crashes.
+The sample with detailed comments can be found here:
+As CodeProject requires registration to download source archive, I have put
+it here:
+Warning: it extracts in the current directory. Use unzip -d.
+Steps to reproduce the problem:
+1. Download and extract
+2. XmlFunctions.cs has "Do something" commented out as placeholders. One
+may want to fill it for debugging purposes.
+3. xbuild
+4. ./bin/Debug/XmlFunctions.exe
+Actual Results:
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+  at System.Xml.XPath.Expression.GetReturnType (System.Object obj) [0x00000]
+  at System.Xml.XPath.EqualityExpr.EvaluateBoolean
+(System.Xml.XPath.BaseIterator iter) [0x00000]
+  at System.Xml.XPath.PredicateIterator.MoveNextCore () [0x00000]
+  at System.Xml.XPath.BaseIterator.MoveNext () [0x00000]
+  at System.Xml.XPath.SlashIterator.MoveNextCore () [0x00000]
+  at System.Xml.XPath.BaseIterator.MoveNext () [0x00000]
+  at System.Xml.XPath.XPathNodeIterator+<>c__CompilerGenerated3.MoveNext ()
+  at XmlFunctions.XmlFunctions.FindAddressForTypeWithVariable
+(System.String type) [0x00000]
+  at XmlFunctions.Program.Main (System.String[] args) [0x00000]
+Expected Results:
+No output. (Confirmed on MS.NET.)
