Hi all,

Im using boost serialization to serialize a base class and his derived
classes. Like this:

ParameterList is a list of parameters and parameters could be different
types of parameters (string, blah blah blah).

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:

// create and open a character archive for output
std::ofstream ofs(dataFilename.str().c_str(), std::ios::binary |
std::ios::app);
boost::archive::binary_oarchive persistenceFile(ofs);
persistenceFile << activeMessage;
logMessage << "Object serialized :" << activeMessage.getText() << "in
position " << lastWrote;

Valgrind shows me this information:

what could be? any idea?
