+Summary: CS1648: setting value to non-readonly member of readonly field fails
+
+Current mcs restricts access to non-readonly field of readonly field (in
+the code below, Foo is readonly in Test, but Value is not readonly in Foo).
+In csc, there is no such restriction propagation.
+
+using System;
+
+public class Test
+{
+        public readonly FooType Foo;
+
+        public void Run ()
+        {
+                Foo.Value = "a";
+                Foo.Value = "b";
+        }
+}
+
+public class FooType
+{
+        public string Value;
+}
+
+
+Actual Results:
+cs1648.cs(9) error CS1648: Members of readonly field 'Test.Foo' cannot be
+assign
+ed to (except in a constructor or a variable initializer)
+cs1648.cs(10) error CS1648: Members of readonly field 'Test.Foo' cannot be
+assig
+ned to (except in a constructor or a variable initializer)
+Compilation failed: 2 error(s), 0 warnings
+
+Expected Results:
+no CS1648 error (CS5001: entrypoint not found)
+
+
+How often does this happen? 
+consistently.
