+Summary: Exception Thrown in Mono, Not Thrown in MS .NET
+
+Description of Problem:
+Whilst trying some regular expressions I came across a difference between
+the MS Runtime and the Mono Runtime. Mono throws a System.ArgumentException
+in the regular expressions library where MS .NET does not.
+
+This is a tiny testcase:
+
+Steps to reproduce the problem:
+1. Compile the follwing code in mcs or csc:
+--- test.cs ---
+using System;
+using System.Text.RegularExpressions;
+
+public class Test
+{
+	public static void Main()
+	{
+		string s = Regex.Replace("", @"\\", @"\");
+	}
+}
+--- eof ---
+2. Execute the code.
+
+Actual Results:
+Exception is thrown in mono.
+
+Expected Results:
+No exception is thrown in MS .NET and the program exits.
