+Summary: gmcs throws a nullref on 'class Outer : IEnumerator<Outer.Inner>'
+
+gmcs will crash with a NullReferenceException if it encounters a class
+definition like this:
+
+public class Outer : IEnumerable<Outer.Inner>
+{
+    public class Inner 
+    { ... }
+
+    ...
+}
+
+Changing IEnumerable<Outer.Inner> to just IEnumerable (even with both the
+generic and non-generic GetEnumerator implementations present) causes the
+code to build and run as expected (minus the obvious generic restriction).
+
+Here's the crash:
+
+aaron at sledipus:~$ gmcs enumerate-nested-class.cs 
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object

+
+Tested on gmcs 1.1.13.8 (SLED) and 1.1.16.1 (Ubuntu Edgy) with the same
+result. I don't have 1.1.17 or HEAD installed anymore at the moment to test
+there.
