+Summary: Array.Sort (Array, int, int) does not check for invalid arguments
+
+Description of Problem:
+Array.Sort (Array, int, int) does not check for values outside the bounds
+of the array. Thus, when given such arguments an IndexOutOfRange exception
+is thrown. It should throw an ArgumentOutOfRange exception.
+
+Steps to reproduce the problem:
+using System;
+
+public class Bug {
+	public static int Main () {
+		int [] oArrValues = new int [] { 1, 2, 4, 3, 5 };
+		int ret = 3;
+		try {
+			Array.Sort(oArrValues, -1, 3);
+			ret = 2;
+		} catch (ArgumentException ex) {
+			ret = 0;
+		} catch (Exception ex) {
+			ret = 1;
+			Console.WriteLine("Wrong Exception thrown:" + ex.ToString());
+			Console.WriteLine(ex.StackTrace);
+		}
+		return ret;
+	}
+}
+
+Actual Results:
+Wrong Exception thrown:System.IndexOutOfRangeException: Array index is out of r

+
+Expected Results:
+Program should run with no output and should return an exit code of 0.
+
+How often does this happen? 
+Always.
