im having an issue with a project using visual studio pro 2005

if it makes a difference the librarys im using are Qt, pdflib, boost, and some crystal com stuff thorugh activex

my problem is that when I build in release my command line args are parsed fine and my application behaves as expected.

when I build in debug mode, I get an asertion failure as follows

Assertion failed: n == name.size()-2, file libs\program_options\src\options_description.cpp, line 122 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. Pavel
