-Summary: Error compiling a protected virtual method
+Summary: FindMembers fails when there is a nameclash with explicit interfaces
 
 mcs fails compiling tabcontrol2.cs in xsp module.
 
 The problem is that the signature generated for a protected virtual method
 (System.Web.UI.Control::AddParsedSubObject) does not include the
 'hidebysig' modifier.

 Additional Information:
 Mono.Controls.Tabs2 derives from System.Web.UI.UserControl, which derives
 from TemplateControl, which derives from Control (which has that method as
 protected virtual).

+This seems to be a bug in our runtime/class libraries.
+
+When we load from an assembly a type who implements an interface, we
+do not get any visibility on methods with the same name as the methods
+from the interface.
+
+Try the following two files expose this bug.  
+
+Compile like this:
+
+mcs -target:library a.cs 
+mcs -r:a.dll b.cs
+
+And you will get:b.cs(2) error CS0115: `Y.A' no suitable methods found
+to override
+
+Type.FindMembers is not returning the method "A" for some reason.
+
+The above sample works with MCS on Windows.
+
+--- a.cs ---
+interface I { void A (); }
+
+public class X : I {
+	void I.A () {} 
+
+	protected virtual void A () {} 
+}
+------------
+
+--- b.cs ---
+class Y : X{
+	protected override void A () {}
+	static void Main () { }
+}
+------------
