valgrind сообщает о утечке памяти mkl dsyev

Question

Я пытаюсь использовать mkl dsev для вычисления собственных значений и векторов. Я нашел this example from intel.

Это работает, но когда я использую valgrind для его проверки, он дает 1665 строк ошибок.

Это слишком много, поэтому я отправлю его в конце.

Большинство из них являются неинициализированными значениями, которые не имеют значения до тех пор, пока результат будет правильным (исправьте меня, если я ошибаюсь). Что касается меня, это утечка памяти, проявленная valgrind. Я последовал примеру и использовал dsyev в своей собственной программе, и valgrind действовал точно так же.

Я боюсь, что это вызовет проблему, если моя программа будет работать в течение длительного времени.

I in on Ubuntu 14.04, компиляция с icc 13.1.1 с опцией -O0.

Это результат Valgrind (я не знаю, как поставить все в формате, вы можете только читать последние несколько строк):
