11009,Possible memory leak in gregorian::from_simple_string,lszczygielek@…,"James E. King, III","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;
}
}}}
