Patch is reverted for now. The fix wasn't correct (or was incomplete), as

showed by the testcase:



class nullable_int

{

  bool init_;

  union {

    unsigned char for_value_init;

    int value_;

  };

public:

  constexpr nullable_int() : init_(false), for_value_init() {}

};



int main()

{

  nullable_int n;

}
