Hi.

mcs reports this:

| mcs --version
Mono C# compiler version 1.1.8.0
| mcs t.cs
t.cs(8) warning CS0162: Unreachable code detected
Compilation succeeded - 1 warning(s)

But in t.cs, all code is reachable, as can be demonstrated by running the 
program "t hello" and "t":

using System;

class Hello
{
  public Hello()  {  d_n = 0;  }

  public bool Test(int n)
  {
    d_n = 0;
    test(n);
    if (d_n > 0)  {  goto theend;  }
    return false;
theend:
    return true;
  }

  ////// private

  int d_n;

  void test(int n)  {  d_n = n;  }
}

class Test
{
  public static void Main(string[] args)
  {
    Hello h = new Hello();
    Console.WriteLine("result = {0}", h.Test(args.Length));
  }
}

Maybe the compiler has an error somewhere in its reachability computations 
where goto statements are not treated properly with respect to data 
members.

My build setup is for warnings to be treated as errors, so this is a 
fairly iritating problem for me as I do not want to switch back and forth 
between "treat warnings as errors" and "don't treat warnings as errors".
