+I found the crash source, on 'SimpleName.SimpleNameResolve' the
+ec.TypeContainer.TypeBuilder value can be null, and this will cause 
+the call to 'MemberLookup' to crash.
+
+By handling the possible 'null' the crash is avoided.
+if (ec.TypeContainer.TypeBuilder != null)
+	e = MemberLookup (ec, ec.TypeContainer.TypeBuilder, Name, 
+Location);
+
+Once this change is introduced, there is still a type lookup 
+problem, only fully qualified types can be used to reference the 
+items.
+
+In the sample code provided:
+B will fail because A.A_1 is not found.
+C is fine now.
