On aarch64 FreeBSD (see the comment for the failure message):

struct data

virtual ~data() =3D default;
};
void test(std::shared_ptr<data> b)
{
auto dpc =3D std::dynamic_pointer_cast<data>(b);
}
Note: On FreeBSD, I do my own poudriere-devel based port builds
and install the resulting packages. For reference:
