 Hi,
 I've made some unit test to my code where I use date_time and Valgrind
 reports me possible memory leak. Here is code sample:
 {{{
 #include <boost/date_time/gregorian/gregorian.hpp>

 using namespace std;

 int main()
 {
     boost::gregorian::from_simple_string("2015-Jan-1");
     boost::gregorian::from_simple_string("2015-January-1");
     return 0;
 }
 }}}
