我有一个名为＆＃34; StoryPresenter＆＃34;它充当我的模型对象（一个名为＆＃34; Story＆＃34;的类的实例）的包装器，并帮助将模型的数据呈现给我的视图。 StoryPresenter的一个实例包含一个故事的实例，以及以下方法：
def state
if story.school_state_territory.blank?
""
else
" | #{ t(story.school_state_territory) }"
end
end
上面的方法工作正常，但是当我添加Rails i18n方法并刷新浏览器时，我的Rails服务器崩溃了：
Started GET "/stories/drafts" for ::1 at 2016-06-28 10:48:42 -0400
Processing by StoriesController#drafts as HTML
(eval):1: [BUG] Segmentation fault at 0x00000105353028
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]
崩溃后，当我重新启动服务器并刷新浏览器仍然使用i18n方法时，页面会加载，但我看到页面上显示HTML，表示给定的翻译键en.yml文件中缺少该属性。可能会出现警告或类似情况（因为密钥实际上已丢失），但在这种情况下我不会期望Rails服务器崩溃。
崩溃发生后，我在服务器日志中看到以下输出：

通过替换：
找到了一种解决方法（不是基础错误的解决方案）" | #{ t(story.school_state_territory) }"
使用：
" | #{ t(story.school_state_territory) rescue "" }"
似乎来自t的未处理异常导致连锁反应导致崩溃。
Ruby使用longjmp在C中实现异常，这意味着代码执行链停止并且永远不会返回到它的原始位置。
实现服务器时，执行链通常在所谓的“事件循环”或反应器模式中循环。
如果longjmp突然出现此循环，服务器可能（可能会）崩溃或挂起。
这类似于Ruby代码在不处理任何异常时将跳回到堆栈顶部并可能终止进程（返回）。
因此，在从C实现Ruby回调时，保护回调免于任何longjmp或Ruby异常通常很重要。 Ruby MRI为此提供了C API（即rb_protect）。
同样适用于FFI。使用FFI时，在将回调传递给执行回调的FFI函数之前，必须在rescue语句中“回滚”回调。
找到回调处理程序（无论是调用Ruby来处理请求的服务器，还是其他库，例如后台任务库）并提交错误报告都是有益的。
