boost/ptr_container/ptr_sequence_adapter.hpp:671: unreferenced parameters 'first', 'last' when compiled with no assertions

Reported by: anonymous Owned by: Thorsten Ottosen
Milestone: To Be Determined Component: ptr_container
Version: Boost 1.44.0 Severity: Cosmetic
Keywords: Cc:


As of r65343 file boost/ptr_container/ptr_sequence_adapter.hpp at function range_check_impl (std::random_access_iterator_tag version), the parameters 'first' and 'last' are referenced only inside a BOOST_ASSERT call. When assertions are compiled out, these parameters become unreferenced. This causes warning C4100 from Microsoft Visual Studio 9. It would be nice to mark the parameters as intentionally unused so that this warning is not generated. The simplest way to do this is to add "(void)first; (void)last;" in the function body. Other more elaborate mechanisms exist, but as far as I know, casting to void is a simple and portable way to prevent the warning without disrupting the debug code's access to these variables.
