The following code compiles in MS.Net, but not in gmcs as of the 2.2 branch. It
does compile correctly in at least 1.9, which I have on hand; and I believe 2.0
which I think I had working yesterday.


using System;

namespace Test
{

    public interface IFoo
    {

    }

    public class Foo : IFoo
    {

    }

    public interface IBase
    {

        T Get<T>(object o);

    }

    public class TestClass : IBase
    {

        public T Get<T>(object o)
            where T : IFoo
        {
            return default(T);
        }

        T IBase.Get<T>(object o)
        {
            return default(T);
        }

        public static void Main(string[] args)
        {
            Console.WriteLine(new TestClass().Get<Foo>(null));
        }

    }

}
