调试技巧 —— 如何利用windbg + dump + map分析程序异常

转自:/article/2960604.html

之前碰到论坛里有几个好友，说程序不时的崩溃，什么xxoo不能read的！ 如果光要是这个内存地址，估计你会疯掉~~

所以分享一下基本的调试技巧，需要准备的工具有WinDbg + VC6.0，

下面是自己整理的一份自动生成DUMP文件的源代码，只需要添加到工程即可，源代码如下：

2、设置VC编译选项，勾选生成MAP和Debug Info:



3、将编译生成的Release目录中的pdb、map文件保存起来，以后调试会用到：



4、运行程序，单击确定按钮出现异常后自动重启，并创建一个Log文件夹，里面生成dump文件:



5、我们打开WinDbg，设置一下pdb路径(File \ Symbol File Path)：



6、用WiinDbg打开dump文件（File \ Open Crash Dump）



7、输入命令!analyze -v，等待几秒后会打印出错误信息，函数调用栈如下图：



OK ，这样我们就能在发布版本的程序中，准确的定位到哪个函数出了问题，所以发布程序时，一定要记得生成pdb、map文件，不然客户运行出错的话，你不死也残！
