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 <boost/date_time/gregorian/gregorian.hpp> 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 ==2382== Memcheck, a memory error detector. ==2382== Copyright (C) 2002-2007, and GNU GPL'd, by Julian Seward et al. ==2382== Using LibVEX rev 1732, a library for dynamic binary translation. ==2382== Copyright (C) 2004-2007, and GNU GPL'd, by OpenWorks LLP. ==2382== Using valgrind-3.2.3, a dynamic binary instrumentation framework. ==2382== Copyright (C) 2000-2007, and GNU GPL'd, by Julian Seward et al. ==2382== For more details, rerun with: -v ==2382== 2007-Feb-03 2007-Feb-07 [2007-Feb-03/2007-Feb-06] ==2382== ==2382== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 7 from 1) ==2382== malloc/free: in use at exit: 856 bytes in 26 blocks. ==2382== malloc/free: 58 allocs, 32 frees, 2,772 bytes allocated. ==2382== For counts of detected errors, rerun with: -v ==2382== searching for pointers to 26 not-freed blocks. ==2382== checked 107,996 bytes. ==2382== ==2382== 20 bytes in 1 blocks are still reachable in loss record 1 of 7 ==2382== at 0x4021FB4: operator new(unsigned) (in /usr/lib/valgrind/x86-linux/vgpreload_memcheck.so) ==2382== by 0x8049CDD: std::locale::locale<boost::date_time::date_facet<boost::gregorian::date, char, std::ostreambuf_iterator<char, std::char_traits<char> > > >(std::locale const&, boost::date_time::date_facet<boost::gregorian::date, char, std::ostreambuf_iterator<char, std::char_traits<char> > >*) (locale_classes.h:568) ==2382== by 0x804F4E2: std::basic_ostream<char, std::char_traits<char> >& boost::gregorian::operator<< <char, std::char_traits<char>
