Antoine Pitrou commented on ARROW-3873:
---------------------------------------
My attempts crash on macOS. The explanation is as following: even if you duly
export template classes such as {{NumericBuilder<Int32Type>}}, they will be
compiled independently in several places, so the resulting typeids will be
different. This makes {{dynamic_cast}} attempts fail when they do not use the
same typeid for the template class.
