Valgrind: неверное чтение размера 4, ошибка сегфоута вне пределов
У меня ошибка segfault в моем многопоточном проекте.
Этот проект является циклической программой, которая должна выполняться непрерывно. Она имеет ЗАДАЧИ, которые в свою очередь состоят из одной или нескольких ОПЕРАЦИЙ.
Запустив Valgrind, я получаю предупреждения об утечке памяти и за ее пределами (недопустимое чтение размера 4).

Метод, в котором сообщается об ошибке, это просто метод Get, который возвращает беззнаковую переменную int.
Решение
Так в чем именно твой вопрос?
Было бы очень полезно, если бы вы добавляли имена файлов и номера строк вместе с вашим кодом, чтобы люди могли сопоставить ваш код с номерами строк из вывода valgrind.
это
==30039== Invalid read of size 4
==30039== at 0x8081714: SISCAT::TaskCycle::GetTasksByTick(unsigned int, std::vector<SISCAT::Task*, std::allocator<SISCAT::Task*> >&) (TaskCycle.cpp:52)
вероятно, означает, что вы обращаетесь к нулевому указателю или к унифицированному указателю в строке 52, и это
==30039== Invalid read of size 4
==30039== at 0x4984BE5: std::_Rb_tree_increment(std::_Rb_tree_node_base*) (in /usr/lib/i386-linux-gnu/libstdc++.so.6.0.16)
==30039== by 0x80817A9: SISCAT::TaskCycle::GetTasksByTick(unsigned int, std::vector<SISCAT::Task*, std::allocator<SISCAT::Task*> >&) (TaskCycle.cpp:63)
очень намекает на передачу пустого указателя на std::_Rb_tree_increment, Но так как мы не видим, какие у вас строки с номерами 52 и 63 в TaskCycle.cpp, мы не можем с этим сильно помочь.
На вашем месте я бы использовал отладчик или добавил бы что-то вроде printf("xxx=%p\n", xxx) ко всем номерам строк, о которых сообщает valgrind (замените xxx всеми указателями, которые используются в этих строках), чтобы вы могли увидеть, какие из них кажутся неправильными.
