5446	Exception thrown by tz_database::load_from_file() on linux 2.6.37, boost1.46.1,gcc4.5.2	frankrq2009@…	az_sw_dude	"Hi, I tried to run the Flight Time Example in boost_1_46_1/doc/html/date_time/examples.html#date_time.examples.simple_time_zone, and an exception was thrown with error message:
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast> >'
  what():  bad lexical cast: source type value could not be interpreted as target
When I debug with step into, I found it happened on line ""Africa/Cairo"" of the date_time_zonespec.csv, because this is the first timezone which needs to call dst_adjustment_offsets(), and there was a '\r' at the end of the line, then when str_from_delimited_time_duration() called boost::lexical_cast<unsigned short>(*beg) the '\r' made the exception being raised. 
On linux, std::getline(ifs, buff) in load_from_file() will leave the '\r' in buff, which caused the exception. On win32 this would not happen. So the line ends '\r' needs to be removed in load_from_file() or at the beginning of parse_string().     "	Bugs	new	To Be Determined	date_time	Boost 1.46.1	Problem
