[C++-sig] Complaint about missing call policies, when they are in fact specified

[Davidson, Josh]

I'm adding return value call policies to methods of a class as follows:
        mb.class_("SerialStore").member_functions(lambda decl: decl.name.startswith("getSim")).call_policies = \
            call_policies.return_internal_reference()

--------------------------------------------------------------------------------------------------------------------------

During generation, I get the following warning:
WARNING: boost::container::list<unsigned char,boost::interprocess::allocator<unsigned char, boost::interprocess::segment_manager<char, boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family, boost::interprocess::offset_ptr<void>, 0ull>, boost::interprocess::iset_index> > > * SerialStore::getSimicsInput() [member function]

Here is the generated code for that method that appears to have the call policy specified:
        { //::SerialStore::getSimicsInput
        
            typedef ::boost::container::list<unsigned char,boost::interprocess::allocator<unsigned char, boost::interprocess::segment_manager<char, boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family, boost::interprocess::offset_ptr<void>, 0ull>, boost::interprocess::iset_index> > > * ( ::SerialStore::*getSimicsInput_function_type )(  ) ;
            
            SerialStore_exposer.def( 
                "getSimicsInput"
                , getSimicsInput_function_type( &::SerialStore::getSimicsInput )
                , bp::return_internal_reference< >() );
        
        }
