看了7cat转了个贴子，才发现用VC2005之前有件很重要的事要做，一件非常重要的事情，重要到不做这件事情，你无法使用VC2005。因为：

     2005 CRT memory leaks: std::basic_iostream ( affects std::stringstream, std::fstream, probably others )！！！

    这真是件让人郁闷的事情！下面的代码将重现这个错误：

"Building the Run-Time Libraries, MSDN2 online, http://msdn2.microsoft.com/en-us/library/k9a8ehy3.aspx - How to rebuild the MSVC runtime libraries.

Workaround Steps:
1. Change the relevant constructor in

{C:\Program Files\Microsoft Visual Studio 8}\vc\include\istream and
{C:\Program Files\Microsoft Visual Studio 8}\vc\crt\src\istream
* directory between {} is the location of the MSVC 8 install directory

explicit __CLR_OR_THIS_CALL basic_iostream(basic_streambuf<_Elem,_Traits> *_Strbuf)
: basic_istream<_Elem, _Traits>(_Strbuf, false),
basic_ostream<_Elem, _Traits>(_Noinit, false)
{ // construct from stream buffer pointer
}

注：修改前内容
 explicit __CLR_OR_THIS_CALL basic_iostream(basic_streambuf<_Elem, _Traits> *_Strbuf)
  : basic_istream<_Elem, _Traits>(_Strbuf, false),
   basic_ostream<_Elem, _Traits>(_Strbuf)
  { // construct from stream buffer pointer
  }

2. Change the relevant constructor in

{C:\Program Files\Microsoft Visual Studio 8}\vc\include\ostream and
{C:\Program Files\Microsoft Visual Studio 8}\vc\crt\src\ostream

__CLR_OR_THIS_CALL basic_ostream(_Uninitialized, bool _Addit = true)
{ // construct uninitialized
if (_Addit)
ios_base::_Addstd(this); // suppress for
iostream
}

注修改前内容：
     __CLR_OR_THIS_CALL basic_ostream(_Uninitialized)
      { // construct uninitialized
      ios_base::_Addstd(this);
      }

3. Rebuild the MSVC libraries by running:

{C:\Program Files\Microsoft Visual Studio 8}\vc\crt\src\bldnt.cmd
* See reference link from description for details on rebuilding the MSVC libraries.

注：注意使用前需要设置一个环境变量，makefile文件中有相关说明
    # If your MSVC++ 8.0 installation is not in the default installation path
    # of "\Program Files\Microsoft Visual Studio 8\VC" on the current drive,
    # set the environment variable VCTOOLS to point to the main directory
    # of your installation.  (For example, "set VCTOOLS=C:\VS.NET\VC8")

4. Modify the Visual Studio project files

a. Properties->Linker->Input , "Ignore Specific Libraries" : msvcprt.lib;msvcrt.lib
b. Properties->Linker->Input, "Additional Dependencies" :
"{C:\Program Files\Microsoft Visual Studio 8}\vc\crt\src\build\intel\sample_p.lib"
"{C:\Program Files\Microsoft Visual Studio 8}\vc\crt\src\build\intel\_sample_.lib"
* Refer to reference link from description on details of the file naming.

5. Put the sample_p.dll and _sample_.dll in the same directory as your app ( or follow the rules for side-by-side deployment).
