https://svn.boost.org/trac10/ticket/3412 <p> Added example of code that will give memory leak. The code is tested with MSVC-8.0. When run in debug the program will show three memory leaks. If I set a break point in the void_caster_shortcut constructor the function is run once, but the destructor is never called. </p> <pre class="wiki">#include &lt;stdio.h&gt; #include &lt;tchar.h&gt; #include &lt;crtdbg.h&gt; #include &lt;boost/archive/binary_oarchive.hpp&gt; #include &lt;boost/serialization/export.hpp&gt; class Base { friend class boost::serialization::access; template&lt;class Archive&gt; void serialize(Archive &amp; ar, const unsigned int version) { } virtual void vTest() { } }; class Level1 : public Base { friend class boost::serialization::access; template&lt;class Archive&gt; void serialize(Archive &amp; ar, const unsigned int version) { ar &amp; boost::serialization::base_object&lt;Base&gt;(*this); } }; class Level2 : public Level1 { friend class boost::serialization::access; template&lt;class Archive&gt; void serialize(Archive &amp; ar, const unsigned int version) { ar &amp; boost::serialization::base_object&lt;Level1&gt;(*this); } }; BOOST_CLASS_EXPORT(Base) BOOST_CLASS_EXPORT(Level1) BOOST_CLASS_EXPORT(Level2) int _tmain(int argc, _TCHAR* argv[]) { _CrtSetDbgFlag(_CRTDBG_LEAK_CHECK_DF); return 0; } </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/3412 Trac 1.4.3 Robert Ramey Sun, 11 Oct 2009 21:11:05 GMT https://svn.boost.org/trac10/ticket/3412#comment:1 https://svn.boost.org/trac10/ticket/3412#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> I've fixed this on my own machine. </p> <p> I don't know if it will get uploaded/tested in time for inclusion in 1.41. </p> <p> Thanks for providing a good test case.

I have updated the example with Level3 and Level4 and get new leaks. See attached file. To make the code easier to debug it is possible to comment out BOOST_CLASS_EXPORT(Level4). Then you only get one leak. </p> Ticket Robert Ramey Sat, 28 Nov 2009 18:58:41 GMT https://svn.boost.org/trac10/ticket/3412#comment:4 https://svn.boost.org/trac10/ticket/3412#comment:4 <ul> <li><strong>status</strong> <span class="trac-field-old">reopened</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> Ticket
