Description of Problem:
A Delegate is invoked when it shouldn't if the method is simple enough.

Steps to reproduce the problem:
1. Place in a file: 
public class A
{
        private int _output     = 0;
        private int _error      = 0;

        public static void Main(string[] args)
        {
                System.Diagnostics.Process process = new
System.Diagnostics.Process();

                process.StartInfo.FileName = "ls";

                process.StartInfo.CreateNoWindow = true;
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.RedirectStandardOutput = true;
                process.StartInfo.RedirectStandardError = true;

                try
                {
                        process.Start();

                        A aux = new A();

                        process.OutputDataReceived += aux.OutputReceived;
                        process.ErrorDataReceived += aux.ErrorReceived;

                        process.BeginOutputReadLine();
                        process.BeginErrorReadLine();

                        process.WaitForExit();

                        process.CancelErrorRead();
                        process.CancelOutputRead();

                        System.Console.WriteLine("Ouput " + aux._output);
                        System.Console.WriteLine("Error " + aux._error);
                }
                finally
                {
                        process.Close();
                }
        }
        private void OutputReceived(object sender,
System.Diagnostics.DataReceivedEventArgs args)
        {
                _output++;
        }
        private void ErrorReceived(object sender,
System.Diagnostics.DataReceivedEventArgs args)
        {
                /*foreach(char a in args.Data)
                        System.Console.WriteLine(a);*/
                _error++;
        }
}

2. 
Compile it and run it.

Actual Results:
Error value is 1.

Expected Results:
Error value should be 0.

How often does this happen? 
Always, except if I add more code to the method as the one inside the comment.
