>Description:
An attempt to create a pointer to a templated member function causes an internal compiler error. See attached minimum code example.
>How-To-Repeat:
class TryIt
{
  public:
    template<typename T> T *create()
    {
      Deletor=destroy<T>;
      return new T;
    }

    template<typename T> void destroy(void *&Ptr)
    {
      Deletor(reinterpret_cast<T *>(Ptr));
    }

  private:
    void (*Deletor)(void *&Ptr);
};

void main()
{
  TryIt Try;
  int *Ptr = Try.create<int>();
}
>Fix:
No workaround found. I'm open to suggestions.
