+NullReferenceException in System.Reflection.Emit.TypeBuilder:CreateType
+when creating Enums
+
+Steps to reproduce the problem:
+
+1. create testcase.cs:
+---------------------------------------------------
+using System.Reflection;
+using System.Reflection.Emit;
+using System.Threading;
+
+class Testcase {
+  public static void Main() {
+    AssemblyName assemblyName = new AssemblyName();
+    assemblyName.Name = "MyAssembly";
+    AssemblyBuilder assemblyBuilder =
+Thread.GetDomain().DefineDynamicAssembly(assemblyName,
+AssemblyBuilderAccess.RunAndSave);
+    ModuleBuilder moduleBuilder =
+assemblyBuilder.DefineDynamicModule(assemblyName.Name + ".dll",
+assemblyName.Name + ".dll", false);
+    TypeBuilder typeBuilder = moduleBuilder.DefineType("MyClass",
+TypeAttributes.Public);
+    EnumBuilder enumBuilder = moduleBuilder.DefineEnum("MyEnum",
+TypeAttributes.Public, typeof(int));
+    typeBuilder.DefineField("myField", enumBuilder, FieldAttributes.Private);
+    typeBuilder.CreateType();
+    enumBuilder.CreateType();
+    assemblyBuilder.Save(assemblyName.Name + ".dll");
+  }
+}
+---------------------------------------------------
+2. mcs testcase.cs
+3. mono testcase.exe
+

+in <0x00004> (wrapper managed-to-native)
+System.Reflection.Emit.TypeBuilder:create_runtime_class
+(System.Reflection.Emit.TypeBuilder)
+in <0x00332> System.Reflection.Emit.TypeBuilder:CreateType ()
+in <0x00154> Testcase:Main ()
+
+
+Expected Results:
