You did not indicate where the library hangs (i.e. did not provide a complete
backtrace). If it's in some threading-related function, it means that you're
using wrong version of the library. If you application is multi-threaded, you
must link to MT build of program_options. One important aspect of this is that
MT mode changes layout of shared_ptr, which is used in program_options public
interface, so mismatch in MT mode between the library and the program causes
sure problems.

Well, this looks reasonable. Do you build your own application in such a way
that Boost things its multi-threaded?
