Comment(by patbob_at_[hidden]):

 I get this bug on Windows (VC++ 7.0 (2005)), boost 1.37.0.  I am linking
 with program_options library.  Perhaps this global is getting defined in
 some random boost library, but it certainly isn't in program_options lib
 where it belongs.

 The value is declared, but not defined.. at least, not in the
 program_options library where it belongs.

 If you get this error, provide an explicit line length to the
 options_description constructor so it doesn't try to use
 m_default_line_length.  Like this:

 po::options_description desc("Options", 1024);

 I'm leaving this bug closed since it probably isn't a proiblem for most
 users... just windows users :)
