--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Why do you think the warning is incorrect in this case?
The warning is about dynamic_cast<Derived*>(var); which can return nullptr
if var doesn't point to Derived object or something derived from it.
In that case, var_ref->empty() will invoke the empty method on nullptr, which
is invalid.
