C ++项目具有精心设计的异常机制(C++ Project with well designed exception mechanism)

有没有人知道一个开源c ++应用程序与一个设计良好/强大的异常机制，所以我可以获得一些灵感？ 我看到的大多数代码/示例都有可疑的事情：

使用消息字符串作为参数抛出对象。 似乎错了，因为它将异常标记为致命，可以向用户显示的错误消息更高，为客户端代码尝试处理异常留下了很小的空间。 即使异常是致命的，像diffirent语言环境（语言）之类的东西也会使得在抛出点处格式化消息对我来说似乎是一个坏主意。
使用从基本异常类派生的大量不同的异常类。 为每一个可能出错的东西（打开文件，读取文件，写入文件，创建线程等）引入一个新的类/类型感觉是错误的。 使用基类型捕获最高级别的所有未处理异常会丢失显示有意义错误消息所需的类型信息。
对每个组件/库使用从基本异常类派生的一个异常类，并为其指定错误代码作为参数以指示确切的错误。 使用基本类型捕获会导致模糊不清。 （我们捕获了谁的错误代码“3”？）...

一些正确方向的指针将受到欢迎。

Does anyone know a opensource c++ application with a well designed/robust exception mechanism so I can get some inspiration? Most code/examples I see do questionable things like:

Throw objects with a message string as argument. Seems wrong because it marks the exception as fatal, a error message wich can be displayed to the user higher up leaves little room for client code trying to handle the exception. Even if the exception is fatal, things like diffirent locales (languages) makes formatting a message at the point of throw seem like a bad idea to me.
Use tons of different exception classes derived from a base exception class. Just feels wrong introducing a new class/type for every single thing that can go wrong (open file, read file, write file, create thread, etc...). Catching all unhandled exceptions at the highest level using the base type loses type information required to display meaningfull error messages.
Use one exception class derived from a base exception class for every component/library and give it a error code as argument to indicate the exact error. Catching with base type results in ambiguity. (Whose error code "3" did we catch? )...

Some pointers in the right direction would be welcome.

 我希望你能：  
$array = [];
$faculty = array(2, 3, 4);
$message = array('test1', 'test2', 'test3');
$id = 1;
for ($key = 0; $key < count($faculty); $key++) {
    $array[$key]['faculty'] = $faculty[$key];
    $array[$key]['message'] = $message[$key];
    $array[$key]['id'] = $id;
}
print_r($array);

I hope this will you: 
$array = [];
$faculty = array(2, 3, 4);
$message = array('test1', 'test2', 'test3');
$id = 1;
for ($key = 0; $key < count($faculty); $key++) {
    $array[$key]['faculty'] = $faculty[$key];
    $array[$key]['message'] = $message[$key];
    $array[$key]['id'] = $id;
}
print_r($array);
