+Summary: disabling obsolete warning in one file makes it crash the compiler in another file
+
+If you put "#pragma warning disable 612" in one file, then the
+compiler will crash if it encounters a warning 612 ("blah is obsolete")
+in another file:
+
+danw@twelve-monkeys:tmp> cat A.cs
+using System;
+ 
+[Obsolete]
+public class One { }
+ 
+#pragma warning disable 612
+ 
+public class Two {
+        private One one;
+}
+
+danw@twelve-monkeys:tmp> cat B.cs
+using System;
+ 
+public class Three {
+        public static void Main ()
+        {
+                One = new One ();
+        }
+}
+
+danw@twelve-monkeys:tmp> mcs -o test.exe A.cs B.cs
+
