Ошибка: нарушения доступа чтения

Имеется программа, которая пересекает 2 многоугольника (std::vector RealSector(1), std::vector MirrorSector(1);). Количество пересеченных точек сокращается (std::vector SendForSaving(1)) до ~50 путем записи в std::vector SendForSaving(1) не всех точек с учетом, что есть так называемые "важные точки" (POINT VIPdots[6]). Все это дело параллельно отрисовывается посередине экрана с помощью метода Polygon (POINT *...). В дополнительном окошке отрисовывается то, что будет сохранено. Возникает проблема при запуске и может выдать 2 вида ошибок (см. рисунки). Обе пишут о нарушении доступа при чтении, хотя, как мне кажется, с выделением и освобождением памяти проблем нет. В чем может быть причина ошибок и как исправить. Спасибо.
