Again, this is not an error.  If you want an error, add these lines:

A a; // ERROR! Can't have a struct with uninitialized reference members.

A* pa;

A a2(*pa); // OK.  The default copy c'tor inits a2.ri with pa->ri.

int i;

A a3={i}; // OK.  Use array initializer to make a3.ri a reference to i.
