Ошибка в CorePlot 1.5.1

Question

Я получаю сообщения от пользователей моего приложения об ошибке внутри структуры CorePlot. Это не всегда происходит, и я не могу обнаружить шаблон, как заставить его разбиться. Я хотел бы знать, есть ли что-то, что я могу сделать, чтобы избежать этого краха.

Я считаю, что проблема была решена. В ближайшее время выйдет релиз 1.6, или вы можете вывести последний код с GitHub.
