Nothing stands out to me. Polymorphic.... hmm... I don't do anything of the sort in my example.
Doesn't really explain why the warning is there does it.
So that readers can follow along... here's extended_type_info_typeid.hpp line 88:
// get the eti record for the true type of this record
// relying upon standard type info implemenation (rtti)
const extended_type_info *
get_derived_extended_type_info(const T & t) const {
// note: this implementation - based on usage of typeid (rtti)
// only does something if the class has at least one virtual function.
BOOST_STATIC_WARNING(boost::is_polymorphic<T>::value);
return
detail::extended_type_info_typeid_0::get_extended_type_info(
typeid(t)
);
