测试例子：

// test123.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include "winDump.h"

int _tmain(int argc, _TCHAR* argv[])
{
	SetMyUnhandledExceptionFilter(L"myTest.dmp");

	char* p=NULL;
	memcpy(p,"this is just dump test",5);
	return 0;
}

运行结果：

启动调试：

用编译器调试(VS)：

1.将dmp拷贝至当时编译的电脑上（如果不在同一台电脑，调试时要指定对应版本的源码 ）

2.将 test123.exe 和 test123.pdb 及 dmp文件放置同一个文件夹中

3.确保原本的编译代码没有改变过，及要有对应版本的代码，

4.F5启动调试，此时就可以在源码中看到崩溃点了。

用windbg调试：

没试过。
