在某些情况下,使用私有构造函数对类进行反序列化不适用于Boost 1.58.在1.57它工作得很好.使用Visual Studio 2013编译时,下面的代码提供以下错误消息.
1> SerializeTest.cpp 1>c:\program files (x86)\vc\include\xmemory0(588): error C2248: 'A::A' : cannot access private member declared in class 'A' 1> c:\projects\serializetest\serializetest.cpp(14) : see declaration of 'A::A' 1> c:\projects\serializetest\serializetest.cpp(9) : see declaration of 'A'

这是Boost回归还是我的疏忽？@H_502_3@
