using System;
using System.Reflection;
using System.Reflection.Emit;


class T {
static void Main ()
{

AppDomain domain;
AssemblyName name;
AssemblyBuilder assembly;
ModuleBuilder module;

TypeBuilder tb;
ConstructorBuilder ctor;
CustomAttributeBuilder cab;

domain = AppDomain.CurrentDomain;
name = new AssemblyName ("test");
assembly = domain.DefineDynamicAssembly (name,
AssemblyBuilderAccess.RunAndSave);
module = assembly.DefineDynamicModule ("module");


tb = module.DefineType ("T");
tb.SetParent (typeof (System.Attribute));

ctor = tb.DefineDefaultConstructor (MethodAttributes.Public);

cab = new CustomAttributeBuilder (ctor, new object [0]);

Console.WriteLine ("SUCCESS");


}
}

Result:
rolf at linux:/mono> gmcs -debug:full test.cs && mono --debug test.exe
test.cs(17,24): warning CS0219: The variable `cab' is assigned but its value is
never used
Compilation succeeded - 1 warning(s)

Marked as Major given that this is currently preventing vbnc from
bootstrapping.
