Good morning,

I want a boost thread to sleep for some nanoseconds. The following
code is a sample that compiles without errors. However, it does not
work as expected and I cannot figure out why. It seems that the
application get stacked when executes the instruction: sleep(time1)
and it does not execute any thing else.

#include <iostream>
#include <boost/thread.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/date_time.hpp>
//Building options:
//-DBOOST_DATE_TIME_POSIX_TIME_STD_CONFIG -lboost_date_time-mt
-lboost_thread-mt
void replay()
{
    boost::posix_time::time_duration time1, time2;

    time1=boost::posix_time::seconds(3);
    std::cout << boost::posix_time::to_simple_string(time1) << std::endl;
    boost::this_thread::sleep(time1);

    time2=boost::posix_time::nanoseconds(987654321);
    std::cout << boost::posix_time::to_simple_string(time2) << std::endl;
    boost::this_thread::sleep(time2);
}
int main(int argc, char* argv[])
{
    boost::thread replaythread(replay);
    replaythread.join();
    return 0;
}

The BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG is a preprocessor definition
required in order to work with nanoseconds
(http://www.boost.org/doc/libs/1_44_0/doc/html/date_time/details.html#date_time.buildinfo).
The thread sleeps perfectly for 3 seconds if you remove the mentioned
definition from the building options and if you also comment out the
code related to nanoseconds (lines 15-17).

Thank you very much for your time
