Ловушка трассировки / точки останова (ядро сброшено) Гткмм

Это домашняя работа

Привет, я использую Gtkmm для Задания, и я хорошо справляюсь со всем этим, но у меня возникает странная проблема в функции, которую я использую для заполнения TreeView. Вы получаете ошибку.

(out: 21185): GLib-ERROR **: /build/buildd/glib2.0-2.32.3/./glib/gmem.c:408: переполнение, выделяющее 3908326912 * 4 байта
Ловушка трассировки / точки останова (ядро сброшено)

Странная часть, однако, заключается в том, что я использую эту функцию для 3 отдельных TreeViews, и это только в моих самых последних я написал, я получаю эту ошибку

я выделил проблему на линию

*m_refTreeModel = Gtk::ListStore::create((*m_columns));

есть идеи, как это могло произойти? Моя программа довольно большая, поэтому показать весь исходный код, связанный с этим, будет сложно. Однако вот функция, в которой эта строка
