SIGABRT问题在valgrind中用C++中的多线程处理11

class MyClass{ 
    public : 
     void runBscGwThread(int); 
    private : 
     std::unique_ptr<std::thread> MyClass_; 
} 


MyClass::Myclass(int bcfId, A::AParam sctpParams): 
      bcfId_(bcfId), 
{ 
    Myclass_.reset(new std::thread([this](){ this->runBscGwThread(bcfId_);})); 
}

偶尔会看到此问题。在析构函数中我做SIGABRT问题在valgrind中用C++中的多线程处理11

Myclass:: ~Myclass(){ 
if (Myclass_->joinable) 
    Myclass_->join(); 
}

的Valgrind的日志低于：

堆栈跟踪似乎表明您正在销毁'MyClass :: runBscGwThread'中的'MyClass'，所以这个线程试图加入它自己。这正确地抛出'system_error' –

Myclass:: ~Myclass(){ 
    if (Myclass_->joinable) 
     Myclass_->join(); 
    }

由于您已将该线程保持为可连接，因此调用线程将等待其完成。

是否需要保持线程可连接，如果没有对资源的并发访问，则可以允许这些线程并行运行。
