(4)、type_info头文件定义了bad_cast异常类型。 参考https://www.tutorialspoint.com/cplusplus/cpp_exceptions_handling.htm C++ Standard Exceptions C++ provides a list of standard exceptions defined in <exception> which we can use in our programs. These are arranged in a parent-child class hierarchy ...
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...

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 stack unwi...
