Hi all,<div><br></div><div>Im using boost serialization to serialize a base class and his derived classes. Like this:</div><div><br></div><div>ParameterList is a list of parameters and parameters could be different types of parameters (string, blah blah blah).</div>

<div><br></div><div><br></div><div>Im serializing well, and everything is going fine but with valdrind I can see a leak and i dont know why, because the way of I am serializing into the file is the same that is made in the tutorial. Like this:</div>

<div><br></div><div><div>// create and open a character archive for output</div><div>std::ofstream ofs(dataFilename.str().c_str(), std::ios::binary | std::ios::app);</div><div>boost::archive::binary_oarchive persistenceFile(ofs);</div>

<div>persistenceFile &lt;&lt; activeMessage;</div><div>logMessage &lt;&lt; &quot;Object serialized :&quot; &lt;&lt; activeMessage.getText() &lt;&lt; &quot;in position &quot; &lt;&lt; lastWrote;</div></div><div><br></div>
<div>
<br></div><div>Valgrind shows me this information:</div><div><br></div><div><br></div><div><div>=6208== 2,200 (2,000 direct, 200 indirect) bytes in 100 blocks are definitely lost in loss record 3 of 7</div><div>==6208==    at 0x40243C5: operator new(unsigned int) (vg_replace_malloc.c:214)</div>
