iterator_range.hpp defines is_singular() if NDEBUG is not defined but it calls is_singular through the BOOST_ASSERT macro. Unfortunately it is possible to enable BOOST_ASSERT and have NDEBUG defined which leads to a compilation error.
To see this compile the iterator_range.cpp example included with the library with the following defines: gcc -DBOOST_ENABLE_ASSERT_HANDLER -I/usr/local/src/boost-trunk/ -DNDEBUG -c iterator_range.cpp
I'll look into this when I get some time. I guess most people write assertions under the implicit assumption that they are either on or off.
I dunno. IIUC part of the motivation for BOOST_ASSERT was to have something that would be tested even when NDEBUG was defined. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
