Description of Problem:

If I try to compile the given code, rather than report an error, mono
throws a Mono.CSharp.InternalErrorException with a horrendous stack trace.


Steps to reproduce the problem:
1. Try to compile the code below:

using System.Collections.Generic;

public class A {
    public static void Foo (IEnumerable<double> a) {
        IEnumerator<double> a_enum = a.GetEnumerator();
        double b = a_enum.Current<double>;
    }
}

// this should be a_enum.Current, not a.enum.Current<double>.  
// the compiler should report the error.

Actual Results:

The stack trace below

Expected Results:

The above code might be legal, or it might not be (I'm not sure).  Either
handle it correctly, or report an error.

How often does this happen? 

Always.
