У меня есть файл с записями, и я хочу отсортировать их, вызвав sort внутри моего проекта.При запуске программы все выглядит нормально, но при попытке проверить leaks с помощью valgrind я получаю много ошибок.Вот код, который я использую для выполнения:
execlp("sort", "-g", "results", (char*) NULL);
results - это файл, который я хочу отсортировать.
И есть ошибки.

Я что-то не так делаю?Я не ошибаюсь ни в каких указателях, и кажется, что ошибки находятся вне моей досягаемости, поскольку они не появляются внутри моего проекта.
