+I fixed this a couple of weeks ago, but the fix exposes a bug in the
+Mono runtime, so it is currently uncommented.
+This is a Mono runtime bug.
+The compiler generates the code correctly if running on Windows, here
+is the output when running on Mono, when trying to compile:
+mono$ mono mcs.exe a.cs
+no implementation for interface method .I::m() in class .Y
+METHOD .ctor()
+METHOD mm()
+METHOD Main(string[])
+** ERROR **: file class.c: line 687 (mono_class_setup_vtable): should
+not be reached
+The code to remove in the compiler is: mcs/pending.cs, in
+			//
+			// Remove the return below to expose the bug, for now, we need the
+runtime to be fixed.
+			//
+			return implementing_ifaces;
+If you remove that, try the example above.  It will also be exposed in
+a corlib compilation.
