--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Somehow GCC is deciding that easyObjects->begin() and end() are dependent types
so you need to use the template keyword for the call to cast.

That is:
auto casted = obj.template cast<T>();

I don't know if GCC is correct here or not.
