用于编写调试日志的ace log_msg.cpp库文件中的访问冲突错误

Question

我有一个使用CORBA/ACE连接两个分布式模块的项目，当我将我的解决方案从MSVS2008传输到MSVS2015时，我遇到了访问冲突错误使用ACE_DEBUG功能项目的写日志，当我跟随代码我发现空指针错误这部分的代码之前是：

if (tracing) 
    this->start_tracing(); 

这是Log_Msg.cpp是王牌库的文件。这里是错误产生的功能：

ssize_t 
ACE_Log_Msg::log (ACE_Log_Record &log_record, 
        int suppress_stderr) 
{ 
    ssize_t result = 0; 

    // Format the message and print it to stderr and/or ship it off to 
    // the log_client daemon, and/or print it to the ostream. Of 
    // course, only print the message if "SILENT" mode is disabled. 
    if (ACE_BIT_DISABLED (ACE_Log_Msg::flags_, 
         ACE_Log_Msg::SILENT)) 
    { 
     bool tracing = this->tracing_enabled(); 
     this->stop_tracing(); 

#if !defined (ACE_WIN32) 
     // Make this block signal-safe. 
     ACE_Log_Msg_Sig_Guard sb; 
#endif /* !ACE_WIN32 */ 

     // Do the callback, if needed, before acquiring the lock 
     // to avoid holding the lock during the callback so we don't 
     // have deadlock if the callback uses the logger. 
     if (ACE_BIT_ENABLED (ACE_Log_Msg::flags_, 
          ACE_Log_Msg::MSG_CALLBACK) 
      && this->msg_callback() != 0) 
     this->msg_callback()->log (log_record); 

     // Make sure that the lock is held during all this. 
     ACE_MT (ACE_GUARD_RETURN (ACE_Recursive_Thread_Mutex, ace_mon, 
           *ACE_Log_Msg_Manager::get_lock(), 
           -1)); 

     if (ACE_BIT_ENABLED (ACE_Log_Msg::flags_, 
          ACE_Log_Msg::STDERR) 
      && !suppress_stderr) // This is taken care of by our caller. 
     log_record.print (ACE_Log_Msg::local_host_, 
          ACE_Log_Msg::flags_, 
          stderr); 

     if (ACE_BIT_ENABLED (ACE_Log_Msg::flags_, ACE_Log_Msg::CUSTOM) || 
      ACE_BIT_ENABLED (ACE_Log_Msg::flags_, ACE_Log_Msg::SYSLOG) || 
      ACE_BIT_ENABLED (ACE_Log_Msg::flags_, ACE_Log_Msg::LOGGER)) 
     { 
      // Be sure that there is a message_queue_, with multiple threads. 
      ACE_MT (ACE_Log_Msg_Manager::init_backend()); 
     } 


     if (ACE_BIT_ENABLED (ACE_Log_Msg::flags_, ACE_Log_Msg::LOGGER) || 
      ACE_BIT_ENABLED (ACE_Log_Msg::flags_, ACE_Log_Msg::SYSLOG)) 
     { 
      result = 
      ACE_Log_Msg_Manager::log_backend_->log (log_record); 
     } 

     if (ACE_BIT_ENABLED (ACE_Log_Msg::flags_, ACE_Log_Msg::CUSTOM) && 
      ACE_Log_Msg_Manager::custom_backend_ != 0) 
     { 
      result = 
      ACE_Log_Msg_Manager::custom_backend_->log (log_record); 
     } 

     // This must come last, after the other two print operations 
     // (see the <ACE_Log_Record::print> method for details). 
     if (ACE_BIT_ENABLED (ACE_Log_Msg::flags_, 
          ACE_Log_Msg::OSTREAM) 
      && this->msg_ostream() != 0) 
     log_record.print (ACE_Log_Msg::local_host_, 
          ACE_Log_Msg::flags_, 
#if defined (ACE_LACKS_IOSTREAM_TOTALLY) 
          static_cast<FILE *> (this->msg_ostream()) 
#else /* ! ACE_LACKS_IOSTREAM_TOTALLY */ 
          *this->msg_ostream() 
#endif /* ! ACE_LACKS_IOSTREAM_TOTALLY */ 
         ); 

     if (tracing) 
     this->start_tracing(); 
    } 

    return result; 
} 

我用__try/__除了和其他异常处理程序，但我无法解决它。我在MSVS2008中没有这样的错误。也许我应该设置一些设置或添加新文件，但我不知道它是什么。

请帮我:(

你明确地必须初始化ACE库。当你有一个定期的main（），我们有一些宏这样做。也许你有一些特殊的主，试图在调用ACE::init();开始和ACE::fini();在最后。请参阅ACE_wrappers/tests/ACE_Init_Test.cpp。

此外，您必须编译ACE/TAO Visual Studio 2015编译器。也许直接升级到Visual Studio 2017，该编译器ACE/TAO支持6.4.3 /2.4.3。
