Steps to reproduce the problem:

using System;
using System.Linq.Expressions;

namespace MonoTest
    class A<TA>
        class B<TB>
            public static void foo()
                Expression<Action> func = () => foo(); // Compiles fine without
this line

            class C<TC>
                static void bar()

    class Program
        static void Main()

Actual Results:
Internal compiler error at test.cs(17,45):: exception caught while emitting
MethodBuilder [C`1::bar]

Unhandled Exception: System.ArgumentException: method declaring type is not a
generic type definition
