+Summary: Regex Parser doesn't throw exception when patterns ends with '\'
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+The regex constructor should throw an exception on this pattern, but 
+doesn't.  See sample.
+
+Steps to reproduce the problem:
+
+using System;
+using System.Text.RegularExpressions;
+
+class Class1
+{
+	static int Main(string[] args)
+	{
+		try {
+			Regex re = new Regex (@"a\", RegexOptions.None);
+		}
+		catch (Exception) {
+			return 0;
+		}
+		return 1;
+	}
+}
+Actual Results:
+On MS.NET it returns 0.  On mono on linux compiled with csc it returns 1.
+
+Expected Results:
+
+0 on both/all.
+
+How often does this happen? 
+
+Always.
