streaming gregorian::date objects to std::cout leaks memory

Description
there seems to be a problem streaming boost::gregorian::date objects to std::cout, but not to std::ostringstream / whilst noting that this could be a valgrind issue
consider the following code
// build : $ g++ -ggdb -Wall -pedantic -Weffc++ test.cc -o test
// run : $ valgrind ./test
// compiler : g++ (Ubuntu 4.4.3-4ubuntu5) 4.4.3
// library : Boost 1.44.0
#include <iostream> // standard io
#include <sstream> // string-streams
#include <boost/date_time/gregorian/gregorian.hpp>
int
main()
{
namespace bg = boost::gregorian; // namespace alias
const bg::date today(2010, bg::Nov, 12); // 'const' not significant
std::ostringstream oss;
oss << today;
std::cout << "today (1) : " << oss.str() << std::endl; // okay
std::cout << "today (2) : " << today << std::endl; // faulty
}

Requested information follows. But now with Boost version 1.45.0. Everything else remains the same:
// build : $ g++ -ggdb -Wall -pedantic -Weffc++ test.cc -o test // run : $ valgrind --leak-check=full ./test // compiler : g++ (Ubuntu 4.4.3-4ubuntu5) 4.4.3 // library : Boost 1.45.0

Just one further thing. I believe I struck the same issue about three releases back. But didn't report because I was extremely busy on my PhD. Sorry.
Note:
See TracTickets
for help on using tickets.
The valgrind report don't help too much. Could you Rerun with --leak-check=full and post the details of leaked memory?
