+Summary: Invalid ArgumentException in Regex constructor
+
+When passing ^[\s\0]*$ to the Cegex constructor the following exception is 
+thrown :
+
+Unhandled Exception: System.ArgumentException: parsing "^[\s\0]*$" - 
+Unterminated [] set.
+Parameter name: ^[\s\0]*$
+in <0x004d7> 
+System.Text.RegularExpressions.Syntax.Parser:ParseCharacterClass 
+(System.Text.RegularExpressions.RegexOptions)
+in <0x0036b> System.Text.RegularExpressions.Syntax.Parser:ParseGroup 
+(System.Text.RegularExpressions.Syntax.Group,System.Text.RegularExpressions
+.RegexOptions,System.Text.RegularExpressions.Syntax.Assertion)
+in <0x0007b> 
+System.Text.RegularExpressions.Syntax.Parser:ParseRegularExpression
+ (string,System.Text.RegularExpressions.RegexOptions)
+in <0x0008d> System.Text.RegularExpressions.Regex:.ctor 
+(string,System.Text.RegularExpressions.RegexOptions)
+in <0x00012> System.Text.RegularExpressions.Regex:.ctor (string)
+in <0x00025> RegexIssue.Test:Main ()
+
+You can reproduce it using the following code fragment :
+
+using System;
+using System.Text.RegularExpressions;
+
+namespace RegexIssue {
+	public class Test {
+		public static void Main() {
+            		Regex r = new Regex(@"^[\s\0]*$");
+            		Console.WriteLine("Whitespace only? " + r.Match(" 
+\0").Success);
+		}
+	}
+}
+
+This works fine on MS.NET.
