많은 연구를 한 후에도 왜 valgrind에서이 오류가 발생했는지 알 수 없습니다. 클래스 스파이크 (의사 이중 링크 목록 구현)가 있습니다Valgrind 잘못된 읽기/쓰기 목록
class spike

int s_cell;
int s_begin;
int s_number;
int s_type;
spike *s_previous;
spike *s_next;
spike *s_origin; // pointer for original spike or itself
// (in the very first spike_data)
spike *s_derive; // pointer for the spike in the derived class
// (note, that sometimes there are 2 or more high
// order spike_data in parallel; the pointer is only to one)
public:

그리고 클래스 spike_data. 그래서 여기있다 ...

, 그것은 내 아니지만, 그것은 여전히 괜찮습니다. 내가 spike_data를 죽이고 싶을 때, 내가 sd_array [i]를 호출 할 때마다 spike => kill()의 소멸자를 호출 할 때마다 마지막에이 코드 버그가 있습니다. 실행 중에 여러 번 사용되었고 모든 계산이 완료되고 메모리를 해제해야하는 시점에서 작동하지 않습니다. 나는 s_origin-> s_derive = NULL을 넣을 때 문제가 있다고 생각한다. 하지만 u는 더 많은 코드가 필요하면
단지 :
이 코드에 들어갈 수있을만큼 용기있는 사람들을 위해 당신에게 많이 감사 요청 ... 그것을 잡을 수 없습니다!

코드 스타일이 클래스의 첫 번째 줄에서 작동하지 않는 이유를 모르겠다. 죄송합니다. 아니면 스타일에 대해 이야기하고 있습니까? 네, 정말 고문이에요. 이 코드 조각을 더보기 좋은 것으로 바꾸려고합니다. 러시아 출신입니다 ^^ – Nikkolasg
변경했습니다. 더 좋습니다. 새 라인 부재로 인해 실패했습니다. ^^ – Eregrith
