Я выполнял тесты с включенным MeasureMemory и получал исключение "NonConstantMemoryUsage".
Я не модифицировал повторы, как это было предложено в сообщении об ошибке. Чего мне не хватает?

Ошибка: не все повторения внутреннего цикла распределяются одинаковое количество раз! Цикл повторений должен использовать постоянное количество распределений. Вы используете значение повторений внутри цикла?
Пока что я прокомментировал код в AllocationMeasurer, который выбрасывал NonConstantMemoryUsage (не уверен, что это хорошая идея!), Чтобы я мог продолжить дальше. Теперь я получаю отрицательное распределение байтов.
