+Summary: [GMCS] using the as operator with a generic parameter
+
+Here's a test case:
+
+public class Foo<T> {
+ public T Do (object o) { return o as T; }
+}
+
+class Driver {
+ static void Main ()
+ {
+ Foo<int> f = new Foo<int> ();
+ f.Do ("something");
+ }
+}
+
+Expected:
+generic-as.cs(2,34): error CS0413: The type parameter 'T' cannot be used
+with the 'as' operator because it does not have a class type constraint nor
+a 'class' constraint
+
+Actual:
+
+Compilation Finished.
