Hi
I do not know if date time leaks or not, but I want to clarify that before I
will send information to libstdc++ bugzilla.
Regards.
The code:
#include <iostream>
#include
int main()
{
using namespace boost::gregorian;
using namespace std;
date b1 (2007,2,3);
date b2 (2007,2,7);
cout << b1 << '\n'; // line 12
cout << b2 << '\n'; // line 13
date_period p1 (b1, b2);
cout << p1 << '\n'; // line 15
}
And the result of:
valgrind --leak-check=full --show-reachable=yes ./main
