+One more thing... When I change assembly attribute to Save only, it
+crashes again:

+using System.Reflection.Emit;

+AppDomain.CurrentDomain.DefineDynamicAssembly(name,
+AssemblyBuilderAccess.Save);
+            ModuleBuilder mb = builder.DefineDynamicModule("out",
+"bla.dll");
+            ///////////

+TypeAttributes.Abstract);
+            GenericTypeParameterBuilder[] func_gp =
+func.DefineGenericParameters("'a");
+            func.SetParent(typeof (object));

+MethodAttributes.Public | MethodAttributes.Abstract |
+MethodAttributes.Virtual,
+                 func_gp[0], new Type[] { });
+
+            Type func_c = func.CreateType();

+GetGenericTypeDefinition()
+            //Type func_string = func_c.GetGenericTypeDefinition
