我想定位异常到指定的代码行，发现第五步存在问题。希望解答。
步骤：
一、 Symbol file path: srv*;D:\github\MoltenPoolTrack\Bulid\Release\release
其中D:\github\MoltenPoolTrack\Bulid\Release\release是pdb文件的路径
二、 Source path: D:\github\MoltenPoolTrack
其中D:\github\MoltenPoolTrack是源文件的路径
三、 Open crash dump
四、 !analyze -v，下面可以看出是CMyProcess::run+0x45处出现了0xc0000005的异常。
