3 e 6b09cc41 0001 (0001) MF!CASFBytewiseMediaSource::DropSamples
首先我下了两个断点，bl看了下似乎都成功了，但是断点3(DropSamples)不会停下来.
不过我也不是很肯定断点3是不是真的被执行到了，但是我认为应该会被执行的。
然后我发现断点2和3有一些区别，这个好像是导致断点3其实并没有被成功设置。发出来求助一下。
断点3这个地址6b09cc41在我bp的时候其实还根本不在内存里面，所以cc也无法被写进去。
实验如下
1: kd> u MF!CASFBytewiseMediaSource::DropSamples
MF!CASFBytewiseMediaSource::DropSamples:
6b09cc41 ?? ???
^ Memory access error in 'u MF!CASFBytewiseMediaSource::DropSamples'

如果我的分析是对的，那么怎么样才能成功的设置这样的断点呢？
