Michal Malecki <ethouris at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ethouris at gmail dot com --- Comment #3 from Michal Malecki <ethouris at gmail dot com> 2012-01-04 14:52:56 UTC --- I found a case of similar case - different line number, so maybe it's something else: template <size_t B, typename Type1, typename... Types> struct tuple_sliced { typedef typename tuple_sliced<B-1, Types...>::type type; }; template<typename... Types> struct tuple_sliced<0, Types...> // <-- line 18 { typedef tuple<Types...> type; }; gcc 4.6 says that it's not implemented to expand "Types..." in the first structure. I got a message: tuple.cc:18:8: internal compiler error: in process_partial_specialization, at cp/pt.c:4398 The master declaration of tuple_sliced passes correctly - however any use of it will result in infinite recursion when there's no terminal version.
