Я получаю coredump при печати ostream-объектов в файле, детали обратной трассировки:

}

Код Stats.h 

void printSummary(std::ostream &out = std::cout){
.....
   out << m_current.tv_sec << "," <<  lastHbtTime << "," << maxOrderPerSlidingSec << "," << totalActiveOrders << endl;
----
}

FixParser. cpp

std::ofstream statsFile;
std::string fname = "fix_" + gConfig["colo_ip"] +"_" + getToday();
statsFile.open(fname, std::ios::app | std::ios::out);
......
..
printSummary(statsFile);                   
....
..

Я не могу решить эту проблему с дампом ядра, если кто-то может помочь, это было бы здорово, Если я попробую std::cout, код работает отлично.
