I had a same problem with MSVC 2005 when one of my other(no boost) libs use UNICODE.
There is probably some bug in auto_link.hpp (when it generate library name and link it => some link mismach in boost STL raised).
My tricky solution is: Turn off auto_link by statement before include program_option.hpp:
#define BOOST_PROGRAM_OPTIONS_NO_LIB ON
#include <boost/program_options.hpp>
And link library which you need manually (probably libboost_program_options-vc80-mt-gd-1_34.lib) by option Link\Input\additional dependency.
There is a paradox: same library as is normaly included by auto_link can be used to include by MSVC option and then all see OK with no assertion.
