1. 问题 一个C++ 程序,如果 throw 了 exception ,但是又没有 catch,那么一般会产生 coredump, 问题是,在 gcc 4.x 版本产生的 coredump 文件中,没有 throw 时候的堆栈信息,导致不知道是哪里 throw 的,没法查问题。 原因是 gcc 4.x 的 /libstdc++-v3/src/c++11/thread.cc:92 里面有个 catch(…),所以 ...
1. 保证运行时,只会throw listed exception,而如果发生不listed 的exception,那就调用unexpected; 2. 允许或者禁止编译器不得不进行是否listed exception发生的检查。 在上面说明了使用throw时,编译器需要生成try-catch代码, 其实throw还有其他问题:1. 有些编译器会自动拒绝为使用throw的function做inline优化;2. 有些...

注:本文将引用大量白杨前辈的文章:http://baiy.cn/doc/cpp/inside_exception.htm 对于一个编译型语言来说,它为你提供了什么样的特性,那就肯定要执行体现出这样特性的代码,而要想执行体现出这样特性的代码,就一定存在某个机制,让程序需要体现这个特性的时候,能够确定体现该特性的程序入口。
