错误搜寻提示：错误 C2248: 'std::basic_ios<_elem ,_traits>::basic_ios' : 无法访问类中声明的私有成员
我正在将一个大型 VC++ 6.0 应用程序转换为 VS2010，并在其中一个项目中不断遇到此错误：
error C2248: 'std::basic_ios<_Elem,_Traits>::basic_ios' : cannot access private member declared in class 'std::basic_ios<_Elem,_Traits>'
1> with
1> [
1> _Elem=char,
1> _Traits=std::char_traits<char>
1> ]
1> c:\program files (x86)\microsoft visual studio 10.0\vc\include\ios(176) : see declaration of 'std::basic_ios<_Elem,_Traits>::basic_ios'
1> with
1> [
1> _Elem=char,
1> _Traits=std::char_traits<char>
1> ]
1> This diagnostic occurred in the compiler generated function 'std::basic_ofstream<_Elem,_Traits>::basic_ofstream(const std::basic_ofstream<_Elem,_Traits> &)'
1> with
1> [
1> _Elem=char,
1> _Traits=std::char_traits<char>
1> ]
根据错误文本和此处提出的类似问题，我假设该错误是由 ofstream 直接传递到函数中，而不是通过引用传递。
我遇到的问题是，找到以错误方式传递 ofstream 的代码行。错误消息仅链接到 VS2010 中包含的 fstream 标头，而我的项目在数万行代码（都不是我编写的）的代码库中到处使用 ofstream 。
我非常感谢任何帮助/提示/策略来定位此类编译器错误。您将如何解决定位此类错误的问题？
I am converting a large VC++ 6.0 application to VS2010 and keep running into this error for one of the projects:

Based on the error text and similar questions asked here, I assume that the error is caused by an instance of ofstream passed directly into a functions, instead of being passed by reference.
The problem I have is, to locate the line of code in which the ofstream is passed in the wrong way. The error message only links to the fstream header included in VS2010 and my project uses ofstream all over the place in a code base of several tens of thousand lines of code (none of which written by me).
I would greatly appriciate any help / tips / strategies to locate this type of compiler error. How would you approach the problem of locating this kind of error?
