How to synchronize the pointer obtained by the array object with the pointer obtained by the device<>().

[林贞浩]

TEST_CASE("device2") {
double data[] = {1.0, 2.0, 3.0, 4.0, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24};
array *a = new array(2, 3, 4, data);

auto d = a->device<double>();
d[0] = 2;
// af::sync();
a->unlock();
CHECK((*a)(0, 0, 0).scalar<double>() == 2);

*a+=1;
af::sync();
CHECK((*a)(0, 0, 0).scalar<double>() == 3);
CHECK(d[2]==3.0);
auto d2 = a->device<double>();
CHECK(d2[2]==4.0);
}

I would expect CHECK(d[2]==4.0);
