How to debug a Visual C++ Runtime Error
一个程序总算是把一些异常崩溃这些弄得差不多了，能够长时间稳定运行了，但是还是会随机出现崩溃这个问题，而且崩溃了没提供调试选项，没有装VS，只有复制个windbg过去，然后出现断点 查看堆栈信息

明显不对啊，没有出现异常的情况啊，想想还是google一些在stackoverflow看到一些，但是感觉也没啥用啊
转念一想，这个崩溃好像和之前的不一样，没提供调试选项 就一个 确定按钮 然后 是不是windbg断在其他的线程了呢？
查看所有线程堆栈,发现线程很多。。。。。。。。。。
怎么才能找到崩溃的线程，看着那个对话框 想到应该是个MessageBox找一下有的，看哈堆栈 在看哈参数好像就是这个线程1

嗯，继续调哈具体是那里bug吧
调试流程和这个比较像深夜调试某浏览器内存损坏的小记录就不写了1
