Reduced case [Forwarding captured variadic arguments inside lambda] :
https://godbolt.org/g/D7lXEA
template<typename... T>
int g(T... t)
{
return 0;
}
template<class... Args>
void f(Args&&... args)
{
auto lm = [&](auto&&..._args) {
auto f = [&]{g(std::forward<decltype(_args)>(_args)...);};
//auto f = [&]{g(_args...);}; /* THIS ONE OK */
return f();
};
lm(args...);
}
int main()
{
f(2, 5, 7);
}
Error "_args was not declared" on 4.9.x
ICE on 5.x
Ok on 6.x
