I don't think g_slist_free() is problematic here. My guess would be that you're not freeing your data that is pointed to by list elements. g_slist_free() will only free memory that is used by GSList structs, data that is pointed to by data member of GSList structure needs to be freed separately. For example, take gtk_icon_view_get_selected_items() func. Usual usage is: GSList *items = gtk_icon_view_get_selected_items (icon_view); /* Do something here */ g_slist_foreach (items, (GFunc)gtk_tree_path_free, NULL); g_slist_free (items); The important line is g_slist_foreach() line, where actual data that is pointed to by nodes is freed.
