3876	%T format specifier with local_time_facet crashes with MSVC 9	Claudio Bley	az_sw_dude	"The following program crashes with MSVC9 when trying to write the local_date_time to the stringstream:
{{{
#!cpp
#include <boost/date_time/local_time/local_time.hpp> 
#include <iostream>
#include <string>
#include <sstream>

int
main()
{
    using namespace boost::posix_time;
    using namespace boost::local_time;

    time_zone_ptr utc;
    local_date_time now(microsec_clock::universal_time(), utc);

    local_time_facet* output_facet = new local_time_facet();
    local_time_input_facet* input_facet = new local_time_input_facet();

    std::stringstream ss;
    ss.imbue(std::locale(std::locale::classic(), output_facet));
    ss.imbue(std::locale(ss.getloc(), input_facet)); 

    // http://www.boost.org/doc/libs/1_41_0/doc/html/date_time/date_time_io.html#date_time.format_flags
    // %T !  The time in 24-hour notation (%H:%M:%S)
    output_facet->format(""%T"");

    ss << now; // crash in _Strftime_l
}
}}}

With MinGW 4.4.0 it just ignores the %T format specifier. What's the deal with %T?"	Bugs	closed	Boost 1.42.0	date_time	Boost 1.41.0	Problem	fixed
