[Windows]_[0基础]_[Release程序的崩溃报告minidump解决方式]

场景:

1. Release的程序崩溃时，崩溃报告能够让开发者查明代码哪里出了问题，用处大大的。

2. 仅仅实用VS的编译器才支持，所以MinGW就无缘了。

3. 使用了未处理异常过滤处理函数.

4. 生成的.dmp文件用zlib库压缩, 用到下面的ZipHelper类，编译时还是须要zlib库和dbghelp.lib

5. 使用方式就是把DbgReport作为app类的成员变量，或者文件范围的全局变量初始化后，在程序执行開始前调用

RegisterCrashFilter

6. 更新: 添加VC CRT异常捕抓. 2015-09-25
