GCC seems to mishandle a type template parameter pack appearing in the return type of a pointer to data member NTTP pack: typename ...Ts, Ts S::* ...ms

--- Comment #2 from Jakub Jelinek ---
Slightly reduced:
template struct P;
template
struct P {
static constexpr int size() { return (sizeof(S{}.*ms) + ...); }
int sz;
P() : sz(size()) {}
};
struct A { int x, y; };
auto p = P();
