Hi, I am a newbie to boost and I am trying to develop an application which uses boost thread/mutex/condition/date-time classes. I now get crashes in boost::detail::basic_timed_mutex::unlock. What I suspect at this point of time is that my project settings may be wrong. Can somebody please tell me the right configuration flags etc to use when compiling an application using boost on Windows XP VS 2010. Cheers AJ
