+Summary: mcs should give error for deep cycles in struct
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+A struct should not be allowed to contain a member of its own type, no
+matter how deeply nested it is.
+
+Steps to reproduce the problem:
+1. compile the following:
+
+using System;
+
+struct A
+{
+    B b;
+}
+
+struct B
+{
+    A a;
+}
+
+public class C
+{
+    public static void Main()
+    {
+    }
+
+}
+
+Actual Results:
+
+No error message given.
+
+Expected Results:
+
+You should get a 523 error indicating that there is a cycle in the
+structure layout.
+
+How often does this happen? 
+
+Always, when the nesting is > 1 level deep.  mcs does catch the case when
+the parent type is the same as the member type.
