The following invalid line of code is accepted since gcc 3.4.0: ================================================= template<int> typedef struct A; ================================================= Looks like the new parser caused this.
Confirmed. : Search converges between 2002-12-14-trunk (#159) and 2002-12-29-trunk (#160).
Postponed until GCC 3.4.4.
