lua Show() 中抛 error, 在 C# 中 try-catch 得到， 通过 toluaL_exception() 返回 Lua 调用者 ShowStack()， ShowStack() 中止执行，传递异常到 c# 调用者 OnGUI(), OnGUI()中断执行，打印错误信息。

在 lua 中实例化对象，Awake() 中向lua抛异常：state.ThrowLuaException(e)。 中止了 lua 调用和 OnGUI(), 但是新对象的 Start() 成功调用了。 因为 Awake() 中 catch 了异常，按执行成功处理。 如果 Awake() 中不 catch, Awake() 执行异常，也不会有 Start() 调用，但是lua Instantiate() 执行会成功，打印出对象名。
