模板朋友操作员新mingw32

Question

我的理解是operator new不能被模板化（当使用我使用的参数声明时..（size_t）

以下在mingw32和arduino DUE上编译正常，但在其他平台上没有，例如Linux操作系统。

mingw32中是否有错误，或者其他目标是否也允许这样做？

class t_other_class
{
  public:

  // This form of operator new is ***NOT*** allowed to be templated.
  void*                  operator new     ( size_t            arg1  ) ;

  // This form of operator new CAN be templated, and IS.
  template<typename TF>
  void*                  operator new     ( size_t            arg1
                                          , int               arg2
                                          ) ;

  // This form of operator new CAN be templated, but IS NOT.
  void*                  operator new     ( size_t            arg1
                                          , int               arg2
                                          , int               arg3
                                          ) ;
};



template <typename TCLASS>
class t_class
{
  public:

    // This form of operator new can NOT be templated, but is ALLOWED in mingw32
    template<typename TF> // THIS SHOULD GENERATE AN ERROR
    friend
    void*   t_other_class::operator new   ( size_t            arg1  ) ;


    // Examples of templating..
    template<typename TF>
    friend  /* IS templated in t_other_class*/
    void*   t_other_class::operator new   ( size_t            arg1
                                          , int               arg2
                                          ) ;
    template<typename TF>
    friend  /* IS NOT templated in t_other_class*/
    void*                  operator new   ( size_t            arg1
                                          , int               arg2
                                          , int               arg3
                                          ) ;
} ;

我更新到最新的Mingw，它现在正确地报告了模板声明的滥用（按照其他编译器）。看起来老版本的mingw就是问题。
