Terrific, so what does gmThread look like?

Wasn't sure whether you'd want it all pasted! Here it is:

Code:

/// \class gmThread
/// \brief gmThread.. try to keep this class's memory footprint small.. at the time of this comment, its
///        76 bytes.
class gmThread : public gmListDoubleNode<gmThread>, public gmHashNode<int, gmThread>
{
public:
  gmThread(gmMachine * a_machine, int a_initialByteSize = GMTHREAD_INITIALBYTESIZE);
  virtual ~gmThread();

  enum State
  {
    RUNNING = 0,
    SLEEPING,
    BLOCKED,
    KILLED,

    EXCEPTION, //!< exception state, for debugging

    SYS_PENDING,
    SYS_YIELD, 
    SYS_EXCEPTION,
  };

  inline const int GetKey() const { return m_id; }

#if GM_USE_INCGC
  void GCScanRoots(gmMachine* a_machine, gmGarbageCollector* a_gc);
#else //GM_USE_INCGC
  /// \brief Mark() will call Mark() for all objects in the stack.
  void Mark(gmuint32 a_mark);
#endif //GM_USE_INCGC

  /// \brief Sys_Execute() will perform execution on this thread.  a this, function references, params and stack
  ///        frame must be pushed before a call to execute will succeed.
  /// \param a_return will be set to the return variable iff Sys_Execute returns gmThread::KILLED. 
  /// \return the new thread state.
  State Sys_Execute(gmVariable * a_return = NULL);

  /// \brief Sys_Reset() will reset the thread.
  void Sys_Reset(int a_id);

  /// \brief Sys_SetState() will set the thread state.
  inline void Sys_SetState(State a_state) { m_state = a_state; }

  /// \brief PushStackFrame will push a stack frame and adjust the instruction and code pointers. 
  ///        If the function to be called is a c bound function, the call will occur within PushStackFrame.
  ///        Before PushStackFrame is called, this, fp, and params must be pushed on the stack.
  /// \param a_numParameters is the number of params pushed after the function ref.
  /// \param a_ip is the current instruction pointer (pointing to instruction after call.) will be adjusted for new function.
  /// \param a_cp is the current code pointer.  will be adjusted for the new function. a_cp MUST be valid if a_ip is valid.
  /// \return gmThreadState
  State PushStackFrame(int a_numParameters, const gmuint8 ** a_ip = NULL, const gmuint8 ** a_cp = NULL);

etc.

This, with changes in red, compiles with gcc 3.4.2 with "g++ -Wall -pedantic -ansi -c xx.cpp"
With an embedded compiler, I get a problem because Nullify() for gmListDoubleNode<T> doesn't have a member function Nullify(). Probably declared in the "GM_INCLUDE_ITERATOR(T)" part, which I don't have.

Code:

#define NULL 0

template <class T>
class gmListDoubleNode;

/// \class gmListDouble
/// \brief Templated intrusive doubly linked list using a sentinal node
template <class T>
class gmListDouble
{
public:

  /// \class Iterator
  class Iterator
  {
  public:

    //    GM_INCLUDE_ITERATOR_KERNEL(T)

    inline Iterator() { m_node = NULL; m_list = NULL; }
    inline Iterator(T * a_node, const gmListDouble * a_list) { m_node = a_node; m_list = a_list; }

    inline void Inc() { m_node = m_list->GetNext(m_node); }
    inline void Dec() { m_node = m_list->GetPrev(m_node); }
    inline bool IsValid() const { return (m_list && m_list->IsValid(m_node)); }

  private:

    T * m_node;
    const gmListDouble * m_list;
  };

  // methods

  inline gmListDouble();
  inline ~gmListDouble();

  inline void InsertAfter(T * a_cursor, T * a_elem);
  inline bool IsValid(const T* a_elem) const { return (a_elem != &m_sentinel); }
  inline T* GetFirst() const { return (T*) m_sentinel.m_next; }
  inline T* GetLast() const { return (T*) m_sentinel.m_prev; }
  inline T* GetNext(const T* a_elem) const { return (T*) a_elem->gmListDoubleNode<T>::m_next; }
  inline T* GetPrev(const T* a_elem) const { return (T*) a_elem->gmListDoubleNode<T>::m_prev; }
  inline bool IsEmpty() const { return (m_sentinel.m_next == &m_sentinel); }
  inline Iterator First(void) const { return Iterator(static_cast<T*>(m_sentinel.m_next), this); }
  inline Iterator Last(void) const { return Iterator(static_cast<T*>(m_sentinel.m_prev), this); }
  
private:

  class gmListDoubleNode<T> m_sentinel;
};


/// \class gmListDoubleNode
/// \brief intrusive node, must inherit this class templated to your class
template <class T>
class gmListDoubleNode
{
public:

  inline gmListDoubleNode() {}

  /// \brief Remove from list.  Allows node to unlink from unknown list.
  inline void RemoveAndNullify()
  {
    m_next->m_prev = m_prev;
    m_prev->m_next = m_next;
    this->Nullify();
  }

 
private: 
  gmListDoubleNode * m_next;
  gmListDoubleNode * m_prev;

  friend class gmListDouble<T>;
};

What happens if you remove the <T> and change :: to ->?

Code:

inline T* GetNext(const T* a_elem) const { return (T*) a_elem->gmListDoubleNode->m_next; }
