Consider the following:


namespace TestGotoLabels
{
  class GotoLabelsTest
  {
    public delegate void MyDelegate();
#if BROKE
    public void TestMethod()
    {
      TestMethod2( delegate()
    {
          goto outLabel;        
       outLabel:
       System.Environment.Exit(0);
    });
    }
#endif
#if WORKS
    public void TestMethod()
    {
      MyDelegate md = delegate()
    {
          goto outLabel;        
       outLabel:
       System.Environment.Exit(0);
    };
      TestMethod2(md);
    }
#endif

      public static void TestMethod2(MyDelegate md)
      {
    md.Invoke();
      }
    }
  } 

 mcs -t:library -d:BROKE gtest.cs
gtest.cs(11,16): error CS0159: The label `outLabel:' could not be found within
the scope of the goto statement
gtest.cs(12,12): warning CS0162: Unreachable code detected
Compilation failed: 1 error(s), 1 warnings


Defining the WORKS symbol causes compilation to succeed.

The BROKE code appears to work in 2.4.4
