Witam.
Piszę tutaj ponieważ mam problem z pewnym crashem podczas clear() w std::list
Mianowicie mam funkcje
void OutputMessagePool::sendAll()
{
boost::recursive_mutex::scoped_lock lockClass(m_outputPoolLock);
OutputMessageList::iterator it;
for(it = m_addQueue.begin(); it != m_addQueue.end();)
{
//drop messages that are older than 10 seconds
if(OTSYS_TIME() - (*it)->getFrame() > 10000)
{
if((*it)->getProtocol())
(*it)->getProtocol()->onSendMessage(*it);
it = m_addQueue.erase(it);
continue;
}
(*it)->setState(OutputMessage::STATE_ALLOCATED);
m_autoSend.push_back(*it);
++it;
}
m_addQueue.clear();
OutputMessageList* m_toSendMessages = new OutputMessageList();
for(it = m_autoSend.begin(); it != m_autoSend.end();)
{
OutputMessage_ptr omsg = (*it);
if(omsg->size() > 1024 || (m_frameTime - omsg->getFrame() > 10))
{
if(omsg->getConnection() && omsg->getProtocol())
omsg->getProtocol()->resetMsg();
m_toSendMessages->push_back(omsg);
it = m_autoSend.erase(it);
}
else
++it;
}
if(!m_toSendMessages->empty())
Tasker::getInstance().addTask(createTask(boost::bind(&OutputMessagePool::autoSendThread, this, m_toSendMessages)));
else
delete m_toSendMessages;
}
Ważne w niej informacje:
OutputMessageList to typedef std::list<OutputMessage_ptr> OutputMessageList;
OutputMessage_ptr to typedef boost::shared_ptr<OutputMessage> OutputMessage_ptr;
OutputMessage to class OutputMessage : public NetworkMessage, boost::noncopyable
Tasker to inny wątek.
Cały plik nagłówkowy jest dostępny tutaj - http://pastebin.com/raw.php?i=ssNify8q
Crash następuje w funkcji autoSendThread
void OutputMessagePool::autoSendThread(OutputMessageList *m_toSendMessagesNow)
{
if(m_toSendMessagesNow) {
for(OutputMessageList::iterator it = m_toSendMessagesNow->begin(); it != m_toSendMessagesNow->end(); ++it)
{
OutputMessage_ptr omsg = (*it);
if(omsg->getConnection())
{
if(!omsg->getConnection()->send(omsg) && omsg->getProtocol())
omsg->getProtocol()->onSendMessage(omsg);
}
}
m_toSendMessagesNow->clear();
delete m_toSendMessagesNow;
}
}
Podczas (co ciekawe) m_toSendMessagesNow->clear(); Występuje on po kilku godzinach działania aplikacji, w tym czasie funkcja ta zostaje wywołana kilkanaście tysięcy razy.

Jeśli byłyby potrzebne dodatkowe dane proszę pisać.
Prosiłbym o poradę dlaczego tak się dzieje, trochę nad tym siedziałem ale nie udaje mi się znaleźć przyczyny.
Pozdrawiam.
