Description of Problem:


Steps to reproduce the problem:
1. Compile this snippet

using System;

namespace MonoTest
{
    public static class GotoCase
    {
        public static void Call(Action<UriKind> func)
        {
        }

        static void Main()
        {
            Call(x =>
            {
                switch (x)
                {
                    case UriKind.Absolute :
                        goto case UriKind.Relative;
                    case UriKind.Relative :
                        break;
                }
            });
        }
    }
}


Actual Results:
Compiler error: test.cs(19,49): error CS0159: The label `case 2:' could not be
found within the scope of the goto statement


Expected Results:
Compilation succeeded

How often does this happen? 
Every time

Additional Information:
Refactoring the lambda into a named method solves the problem.
