I'm going to revert for now the fix for 54922. This one is essentially just a

duplicate of that one, simply trying to use the user defined type:



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;

}
