I have some code which can be compiled fine with Borland, GCC, VC, Intel and CodeWarrior compilers but not in DMC. Digital Mars compiler either has problems with member templates, automatic type deduction in member templates or problems with member function pointers. Below is minimal code which fail in last official 8.38 and last beta of 8.39 relases of DMC:

  class POVMS_Message;
  class MessageReceiver
  {
    protected:
      template<class T> class HandlerOO
      {
        typedef void (T::*HandlerPtr)(POVMS_Message&, POVMS_Message&, int);
      };
      template<class T> class Handler
      {
        typedef void (T::*HandlerPtr)(void *, void *, int);
      };
      MessageReceiver(void *);
      template<class T>
        void InstallFront(T *cptr, typename HandlerOO<T>::HandlerPtr hptr)
        {
        }
      template<class T>
        void InstallFront(T *cptr, typename Handler<T>::HandlerPtr hptr)
        {
        }
  };

  class MessageOutput : public MessageReceiver
  {
    public:
      MessageOutput(void *);
      ~MessageOutput();
      void InitInfo(void *, void *, int);
  };

  MessageOutput::MessageOutput(void * context) : MessageReceiver(context)
  {
    InstallFront(this,  &MessageOutput::InitInfo);
  }



Error message is:


c:\dm\bin\dmc -cpp -c -o -Ae  ..\..\source\frontend\messageoutput.cpp
  InstallFront(this,  &MessageOutput::InitInfo);
                                              ^

Walter, any progress on this? How far the next beta or full release is?

I need a minimal example which reproduces the problem.

Is there anything wrong with minimal example posted at begining of this thread? See http://www.digitalmars.com/drn-bin/wwwnews?c%2B%2B.beta/262

Ah, no, it'll do fine. My mistake.
