That's funny, I've spent the better part of today trying to track a similar issue down. My scenario doesn't involve date_time, however. It uses tokenizer directly (which is getting used indirectly in your case by date_time). But my scenario is complicated, and my efforts to find a simplier repro have failed.
Not a problem in date_time, but certainly a problem either in tokenizer or iterator (or possibly a compiler bug). I'm continuing to investigate.
I saw this error yesterday while fixing another date_time issue. The date_time code that triggered it uses the deprecated tokenizer char_delimiters_separator. (I was planning on fixing that today.)
Could this be part of the problem?
maybe, I get no errors compiling my program now, but I have some new warnings: the two size_t to int ones are pesky, the others, I can't tell if there actually IS any possibility of losing data. ------ Build started: Project: MakeDriveData, Configuration: Debug Win32 ------ Compiling... cyborgdrivecanula.cpp c:\boost\include\boost-1_32\boost\date_time\posix_time\conversion.hpp(27) : warning C4244: 'argument' : conversion from 'time_t' to 'long', possible loss of data c:\boost\include\boost-1_32\boost\date_time\time_system_counted.hpp(57) : warning C4244: 'initializing' : conversion from 'boost::date_time::counted_time_rep<config>::int_type' to 'boost::date_time::gregorian_calendar_base<ymd_type_,date_int_type_>::date_int_type', possible loss of data with [ config=boost::posix_time::millisec_posix_time_system_config ] and [ ymd_type_=boost::gregorian::greg_year_month_day, date_int_type_=boost::date_time::int_adapter<unsigned long>::int_type ] c:\boost\include\boost-1_32\boost\date_time\time_system_counted.hpp(52) : while compiling class-template member function 'boost::date_time::counted_time_rep<config>::date_type boost::date_time::counted_time_rep<config>::date(void) const' with [ config=boost::posix_time::millisec_posix_time_system_config ] c:\boost\include\boost-1_32\boost\date_time\time_system_counted.hpp(111) : see reference to class template instantiation 'boost::date_time::counted_time_rep<config>' being compiled with [ config=boost::posix_time::millisec_posix_time_system_config ] c:\boost\include\boost-1_32\boost\date_time\time.hpp(52) : see reference to class template instantiation 'boost::date_time::counted_time_system<time_rep>' being compiled with [ time_rep=boost::posix_time::int64_time_rep ] c:\boost\include\boost-1_32\boost\date_time\posix_time\ptime.hpp(32) : see reference to class template instantiation 'boost::date_time::base_time<T,time_system>' being compiled with [ T=boost::posix_time::ptime, time_system=boost::posix_time::posix_time_system ] c:\boost\include\boost-1_32\boost\date_time\time_parsing.hpp(81) : warning C4267: 'initializing' : conversion from 'size_t' to 'int', possible loss of data c:\boost\include\boost-1_32\boost\date_time\posix_time\time_parsers.hpp(27) : see reference to function template instantiation 'time_duration boost::date_time::parse_delimited_time_duration<boost::posix_time::time_duration>(const std::string &)' being compiled with [ time_duration=boost::posix_time::time_duration ] c:\boost\include\boost-1_32\boost\date_time\date_parsing.hpp(211) : warning C4244: 'argument' : conversion from 'std::allocator<_Ty>::value_type' to 'char', possible loss of data with [ _Ty=wchar_t ] c:\boost\include\boost-1_32\boost\date_time\date_parsing.hpp(253) : see reference to function template instantiation 'date_type boost::date_time::from_stream_type<date_type,std::basic_string<_Elem,_Traits,_Ax>::iterator>(iterator_type &,iterator_type &,wchar_t)' being compiled with [ date_type=boost::gregorian::date, _Elem=wchar_t, _Traits=std::char_traits<wchar_t>, _Ax=std::allocator<wchar_t>, iterator_type=std::basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t>>::iterator ] c:\boost\include\boost-1_32\boost\date_time\gregorian\parsers.hpp(78) : see reference to function template instantiation 'boost::date_time::period<point_rep,duration_rep> boost::date_time::from_simple_string_type<boost::gregorian::date,wchar_t>(const std::basic_string<_Elem,_Traits,_Ax> &)' being compiled with [ point_rep=boost::gregorian::date, duration_rep=boost::gregorian::date_duration, _Elem=wchar_t, _Traits=std::char_traits<wchar_t>, _Ax=std::allocator<wchar_t> ] Linking...
