shared pointer behavior when container object passed as (void*)

I have shared_ptr variable in my class object (ObjA). There is a requirement where this object is to be stored as (void*) entity of another Class' object (ObjB).

My doubt is, what will be the behavior of shared_ptr (will associated heap memory be freed?, what will happen to its reference count?)-

1. when ObjA is converted to void*

2. when void* entity of ObjB is cast back to (ClassA *)

Simplified Code:

Class AA{

    shared_ptr<int> aptr;

    public:
        AA(){
            aptr = make_shared<int>(100);
        }
        shared_ptr<int> get_aptr(){
            return aptr;
        }
};


Class BB{

    void *smpl;

    public:

        void setter(void* p){
            smpl = p;
        }

        void* getter(){
            return smpl;
        }
};

int main(){

    AA *objA = new AA();
    BB *objB = new BB();

    objB->setter(objA);
    //status of allocated int in class AA here?

    //some code later
    AA *objA_2 = (AA*)objB->getter();
    //status of allocated int in class AA here?

    shared_ptr<int> p2 = objA_2->get_aptr();
    //is this allowed

}
