Использование GCC Undefined Behavior Sanitizer

Question

Сегодня я прочитал an article о GCC Неопределенное поведение Sanitizer (ubsan). Тем не менее, когда я следую шаги там (добавить -fsanitize=undefined в мой код), компилятор (GCC 4.9.2 на Ubuntu 15.04) говорит, что некоторые ссылки не определены:

Как я могу это исправить?

Answer 1

Я установил libubsan0 и lib64ubsan0 и добавил -lubsan вариант, и мое приложение скомпилировано успешно!
