Fix: not known
State-Changed-From-To: open->analyzed State-Changed-Why: Confirmed. gcc 2.95.x and the 3.3 branch emit the following error messages: gcc 2.95.x: bug.cc:6: invalid use of `template <class T> N::C<T>' gcc 3.3-20021230: bug.cc:6: error: invalid use of `template<class T> class N::C' With gcc 3.0.x, 3.1.x, 3.2.x we get an ICE which is clearly a regression on the 3.2 branch. With the new parser we get the following error message: bug.cc:6: error: expected primary-expression which is less descriptive than the error message in gcc 2.95.x, 3.3 branch. IMHO this is also a regression (although not a very severe one).
