I think this is a valid code:
void g(auto... args) {
([args...](auto...){}(args ), ...);
}
void f(auto... args) {
([args ](auto...){}(args...), ...);
}
int main() {
g(0, 1); // this one ICE
f(0, 1); // this one works
}

Here is a C++17 version which crashes from 8.1+:
template<typename ...T>
void g(T... args) {
([args...](auto){}(args), ...);
}
int main() { g(0, 1); }
