Как найти дамп ядра? Сузили до конструкторов и функций

Я получаю ошибку дампа ядра (утечка памяти), и я не уверен, откуда она. Я попытался запустить части программы одновременно и минимизировал проблему. Любая помощь будет оценена. Спасибо

Когда производные классы пытаются вызвать функцию setName, он продолжает генерировать дамп ядра. Откуда идет утечка?
