Call virtual function in constructor

Is there any problem if call virtual function in constructor? For
example:

class A
{
public:
     A()
     {
           setvalue();
     }

    setvalue()
    {
           data = getnumber();
    }

    print() { cout << data << endl;

private:
    virtual int getnumber() {return 100;}
    int data;
}

class B : public A
{
public:
         B() { }

private:
         virtual int getnumber() {return 22222;}

}

int main()
{
     A test1;
     test1.print() ;

     B test2;
     test2.print() ;

}

Thanks.
