Valgrind : 유효하지 않은 크기 4의 읽기, 경계 밖의 segfault 오류

2014-04-01 1 views

내 멀티 스레드 프로젝트에서 segfault 오류가 발생했습니다. 이 프로젝트는 연속적으로 실행되어야하는 순환 프로그램으로, 하나 이상의 작업으로 차례로 구성되는 작업을 갖도록 설계되었습니다.Valgrind : 유효하지 않은 크기 4의 읽기, 경계 밖의 segfault 오류

Valgrind를 실행하면 메모리 누수와 범위를 벗어남 (크기가 잘못 읽음) 경고가 나타납니다.

만약 멀티 스레딩이 책임이 있다고 생각되면,'valgrind --tool = helgrind'를 통해 프로그램을 실행하십시오. 프로그램에는 수많은 메모리 오류가 있으며,이 중 하나 하나는 정의되지 않은 동작을 구성하며 다른 모든 오류를 담당 할 수 있습니다. 선호하는 모든 것을 하나씩 제거해야합니다. –

제 경험상 valgrind는 segfaults를 디버깅하는 데별로 유용하지 않습니다. 프로그램이 여전히 올바르게 작동 하는지를 주기적으로 확인해야하지만, segfault가 있으면 gdb를 사용해야합니다. @lfelipem : 그래서 helgrind가 오류를 찾지 못했습니까? 그건 안심 이군. –

그럼 정확히 무엇이 당신의 질문입니까?

파일 이름과 줄 번호를 코드에 게시하면 사람이 코드를 valgrind 출력의 줄 번호와 일치시킬 수 있습니다.

==30039== at 0x8081714: SISCAT::TaskCycle::GetTasksByTick(unsigned int, std::vector<SISCAT::Task*, std::allocator<SISCAT::Task*> >&) (TaskCycle.cpp:52)

은 아마 당신이 줄 번호 (52)에 널 포인터 또는 초기화되지 포인터를 액세스하는, 그리고 매우 많은이

==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)

힌트가 널 포인터를 전달하는 의미 ~ std::_Rb_tree_increment. 그러나 TaskCycle.cpp에서 52 번째 줄과 63 번째 줄을 볼 수 없기 때문에 그다지 도움이되지 못합니다.

만약 내가 당신이라면 나는 디버거를 사용하거나 valgrind에 의해보고 된 모든 행 번호에 printf("xxx=%p\n", xxx)과 같은 것을 추가합니다 (xxx를 해당 행에 사용 된 모든 포인터로 바꿉니다) 잘못된 것 같습니다.

그러면 'iter'에 문제가있을 가능성이 큽니다. gdb를 실행하고, 52 행에 중단 점을 넣고, 중단 점에 도달하면,'print iter','print * iter','print iter-> second'를 알아 차릴 때까지. GetTasks(). begin()이 NULL을 반환하는지 검사하지 않습니다. 유효한 iterator를 반환하지 않을 가능성이 있습니까? –
