Hi Perry, I added this after the first struct Definer template definition... template <typename C, int cnt> const C Definer<C,cnt>::d; ...and then it worked for me with or without NOT_WORKING. After the partial specialization struct Definer <C, 0> definition... template <typename C> const C Definer<C,0>::d; ...but I'm not certain if it is necessary or not. The code compiled with or without it. If it is necessary, GCC provided it as a gimme. Or perhaps the first template definition provided it. HTH, --Eljay
