+Summary: CustomAttributeBuilder ctor crash
+
+My test case:
+
+using System;
+using System.Reflection;
+using System.Reflection.Emit;
+using System.Threading;
+
+public class FooAttribute : Attribute 
+{
+	public char [] Separator;
+}
+
+
+public class C
+{
+	public static void CtorFourTest ()
+	{
+		AssemblyName asmName = new AssemblyName ();
+		asmName.Name = "TestAssembly.dll";
+
+		AssemblyBuilder asmBuilder = Thread.GetDomain ().DefineDynamicAssembly (
+			asmName , AssemblyBuilderAccess.Run);
+
+		ModuleBuilder modBuilder = asmBuilder.DefineDynamicModule ("TestModule");
+		TypeBuilder typeBuilder = modBuilder.DefineType ("TestType",
+			TypeAttributes.Public);
+
+		Type [] ctorParams = new Type [] { };
+		ConstructorInfo classCtorInfo = typeof (FooAttribute).GetConstructor
+(ctorParams);
+
+		CustomAttributeBuilder typeCABuilder = new CustomAttributeBuilder(
+			classCtorInfo,
+			new object [] { },
+			new PropertyInfo [0],
+			new object [0],
+			typeof(FooAttribute).GetFields (),
+			new object [] { new char [] { 'F' } }
+		); 
+
+		typeBuilder.SetCustomAttribute (typeCABuilder);
+
+		// create the type
+		Type myType = typeBuilder.CreateType ();
+
+		//Now check for the validity of the attributes.
+		object testInstance = Activator.CreateInstance (myType);
+
+		//check the validity of the attribute associated with Print method 
+		object [] customAttrs = myType.GetCustomAttributes (false);
+
+		//Custom Attributes of TestType
+		FooAttribute attr = customAttrs [0] as FooAttribute;
+		Console.WriteLine (attr.Separator);
+	}
+
+	public static void Main ()
+	{
+		CtorFourTest ();
+	}
+}
+
+
+Actual Results:
+
+I get this exception
+
+Unhandled Exception: System.NullReferenceException: Object reference not set to
