Hey, so I have the following IL:

il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Ret);

Which works fine. It basically returns the argument given. This, however:

il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Stloc_0);
il.Emit(OpCodes.Ldloc_0);
il.Emit(OpCodes.Ret);

Does not work. It crashes with the exception "Operation could destabilize the runtime.". Now, I know that the purpose of that is useless but I'm trying to reach my goal by small steps. Why does that not work?

The dynamic type in C# 4.0 is a welcome addition to the language.
