+Summary: Problem in static class initialization
+
+Description of Problem:
+A static class doesn't intiale correctly its fields before its static
+methods are called.
+
+Steps to reproduce the problem:
+1. Insert into a file:
+	public class A
+	{
+		public void X()
+		{
+			System.Console.WriteLine("OK");
+		}
+	}
+	public static class B
+	{
+		protected static A _a = new A();
+
+		public static void X()
+		{
+			_a.X();
+		}	
+	}
+	public class Test
+	{
+		public static void Main(string [] args)
+		{
+			B.X();
+		}
+	}
+2. Compile it normally with gmcs
+3. Execute it
+
+Actual Results:
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
+in <0x0000b> FLMID.Bugs.StaticOne.B:X ()
+in <0x00007> FLMID.Bugs.StaticOne.Test:Main (System.String[] args)
+
+
+Expected Results:
+OK
+
+How often does this happen? 
+Always
+
+Additional Information:
+It works fine on .Net 2.0 Beta1 and even the assembly from it works fine on
+mono. So its really a gmcs problem.
+
+Workarround:
+
+protected static A _a;
+
+static ControllerFactory()
+{
+	_a = new A();
+}
