+Summary: mcs NullRefEx after error
+
+The following code:
+
+struct bar {
+        foo foo;
+}
+
+when compiled by mcs will properly give:
+t.cs(2) error CS0246: Cannot find type 'foo'
+
+
+but also causes a nullrefex in the structcycles:
+
+Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of 
+an object

+
+Leaving this as wishlist as it is minor
