Henri Gough updated ARROW-6817:
-------------------------------
Description:
this dynamic_cast fails for me on Mac using Clang9. Was originally trying to
use TupleFromTable stl function. Though, I'm not sure how the tests pass.
Maybe because they run in Release with NDEBUG
{code:java}
using namespace arrow;
std::shared_ptr<Array> arrptr;
{
auto builder = Int64Builder();
auto st = builder.AppendValues(std::vector<std::int64_t>{1, 2, 3, 45});
auto fst = builder.Finish(&arrptr);
}
std::cout << std::is_polymorphic<FlatArray>::value << std::endl;
std::cout << std::is_polymorphic<Int64Array>::value << std::endl;
std::cout << std::is_base_of<Array, FlatArray>::value << std::endl;
std::cout << std::is_base_of<FlatArray, Int64Array>::value << std::endl;
const auto& iarr = static_cast<const Int64Array&>(*arrptr);
