Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |DUPLICATE Status|UNCONFIRMED |RESOLVED --- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note I think I might have reduced it too far. Here is one which at least removes std::string usage: #include <functional> struct string1{}; using namespace std; template<typename ActionType, typename... Cols> void print_action(function<ActionType*(Cols..., ActionType)> action_factory) {} int main(int argc, char *argv[]) { print_action<string1, char>(function<string1*(char, string1)>()); return 0; } ------ CUT ----- This works on ICC, clang and MSVC. Still fails on the trunk. And this is a dup of bug 56190. *** This bug has been marked as a duplicate of bug 56190 ***
