The following code produces invalid IL code:

class X {
        static void Main ()
        {
                object x = null;
                R (ref x);

        }

        static void R (ref object o)
        {
                o = new Hashtable () {{1,2}};
        }
}

Running this program produces:

Unhandled Exception: System.InvalidProgramException: Invalid IL code in X:R
(object&): IL_001a: ret       


  at X.Main () [0x00000]
