Re: g++ self reference bug

[Thomas Roemke]

Sebastien,

well, my g++ compiles it. Are you sure, you do not really have
something like

    struct mySingltonClass
    {
        static mySingltonClass* pPointer;  // <---- works fine
        int mySingltonClass;                     // <---- causes error
    };

    int main(int argc, char *argv[])
    {
      return 0;
    }
