Compiling the following testcase succeeds with csc but fails with gmcs
(1.1.13.6):

  public delegate void A();

  class B
  {
    void C()
    {
      A a = delegate {
        A b = delegate {
         B c = this;
        };
      };
    }

    static void Main()
    {
      B b = new B();
      b.C();
    }
  }

Steps to reproduce the problem:
1. gmcs testcase.cs

Actual Results:
