相同的代码，在VC6.0和VS2010的不同结果?
利用Win32API要实现一个录音功能，在VC6好使，但VS2010下不能用。为了测试，创建了2个简单的基于dialog 的MFC程序，一个在VC6下，一个在VS2010下。相同的代码，但结果不一样，VC6得到的结果无论是debug或者release都正确，而VS2010下则2中版本都不正确。对比了VC6和VS2010的编译默认优化设置，VC6中release版本Inline function expansion->Only __Inline(/Ob1)，而VS2010中release版本Inline function expansion->Default，如今将VS2010的这个参数设置Inline function expansion->Only __Inline(/Ob1)，则release版本可以得出正确的结果。
这个bug跟踪2个星期了，现在还没有任何头绪，各位帮忙分析一下原因，谢谢！
再次声明，VC6和VS2010下面的代码是一样的
