AIX : 예외를 던지는 이유는 멀티 스레드 코드를 중단합니까?

Question

-pthread로 컴파일 된 코드를 실행할 때 C ++ 예외가 발생하면 중단됩니다.

플랫폼 : AIX 5.3 기술 레벨 8 컴파일러 : GCC 3.4.6 링커 : AIX 링커 1.65.2.4

테스트 코드 :

// exception.cpp
#include <iostream>

class MyException
{
public:
        MyException(){}
        virtual ~MyException(){};
};

void gTest()
{
        throw MyException();
}

int main()
{
        try
        {
                gTest();
        }
        catch(MyException const & ex)
        {
                std::cout << "exception was caught" << std::endl;
        }

        return 0;
}


$ g++ exception.cpp
$ ./a.out
exception was caught
$ g++ -pthread exception.cpp
$ ./a.out
terminate called after throwing an instance of 'MyException'
IOT/Abort trap (core dumped)

비슷한 것을 본 사람이 있습니까?

GCC 4로 업그레이드하는 것이 도움이 될 것이라고 생각하십니까?

IBM의 XL 컴파일러로 전환하는 것은 어떻습니까?

감사.

Answer 1

G ++ 4.3.2는이 문제에 대해 잘 작동하는 것 같습니다. 또한 XLC V10은 작동합니다.

Answer 2

AIX에서 프로그램을 시도했습니다.

Oslevel -r

5200-08

g ++ -버전

G ++ (GCC) 3.3.2

g ++ -o ex -pthread ex.cpp

런타임에서 찾을 수없는 기호가 발생합니다 (pthread_mutex_t)

그러나 당신이 그것을 만들면 :

g ++ -o ex -lpthread ex.cpp

예상 효과로 잘 작동합니다. 이것은 올바른 pthread 라이브러리의 링크 문제 일 수 있다고 생각합니다.
