#9181: memory leak in Date_Time
-----------------------------------+------------------------
 Reporter:  gregory@…              |      Owner:  az_sw_dude
     Type:  Bugs                   |     Status:  new
Milestone:  To Be Determined       |  Component:  date_time
  Version:  Boost 1.48.0           |   Severity:  Problem
 Keywords:  Date_Time memory leak  |
-----------------------------------+------------------------
 It looks like there is a memory leak when streaming Date_Time objects to
 standard output. Consider the following simple code:

 #include <boost/date_time/posix_time/posix_time.hpp>
 #include <iostream>

 using namespace boost::posix_time;

 int main() {
     ptime time(boost::gregorian::date(2013, 9, 30), hours(14) +
 minutes(42));
     std::cout << time << '\n';
     std::cout << time.date() << '\n';
     std::cout << time.date().month() << '\n';
     std::cout << time.time_of_day() << '\n';
 }

 Compiling: g++ -lboost_date_time bug.cpp
 Testing: valgrind ./a.out
