struct S {
  array<int, 1000>vals;
  constexpr S (int _val): vals ({_ val}) {}
};
struct T {
  int val;
  static constexpr S stk = S (100);
  // static const S stk = S (100);
  T (int i): val (stk.vals [i]) {}
  void set (int i) {val = stk.vals [i];}
};

I understand thatstatic const S stk = S (100);is not available for the above code, butstatic constexpr S stk = S (100);I didn't know why using code>did not cause an error.

Does
• static constexpr S stk = S (100);exist at runtime?
• T :: stkis used in two places. Willarrayvalsbe generated in two places?
