Is this piece of code not supported?

#include <iostream>
#include <vector>

class Event {
        virtual Event* clone() const = 0;
        int test2() { return 1024;};

class SpikeEvent : public Event {
        using Event::test2;
        SpikeEvent* clone() const {};

int main() {
   SpikeEvent se;
#pragma omp target parallel for map(to: se)
   for (int i=0;i<1024;i++) {
      printf("%d\n", se.test2());
