+Summary: ref/out overloading mismatch
+
+The following program should not compile, but it does with mcs on both
+runtimes.
+using System;
+
+class T {
+        static void stuff (out object o) {
+                o = 2;
+        }
+        static void stuff2 (ref object o) {
+                o = 2;
+        }
+        static void Main () {
+                object o = 1;
+                stuff (ref o);
+                stuff2 (out o);
+        }
+}
+Note: ref must match with ref, out with out.
+csc gives the following errors:
+ref-out.cs(12,3): error CS1502: The best overloaded method match for
+'T.stuff(out object)' has some invalid arguments
