以上代码是GDB信息; triagens::basics::Utf8Helper::Utf8Helper()没有被称为我的代码。首先，我认为它被3rdParty库调用，并且该方法存在于第三方的源代码中;但是当我搜索{时，我发现它没有被使用{1}}密钥。所以我不知道原因，你能帮助我吗？

Answer 1

@MatthewFisher嗯。我在doLoadFromCommonData上设置了一个断点，但它没有工作，程序没有加入它。我使用＆＃39;导出MALLOC_CHECK_ = 2＆＃39;和＆＃39; ./test＆＃39; ，它产生一个核心.4675。使用＆＃39; gdb ./test core.4675＆＃39; ＆＃39;在哪里＆＃39;制作了一段：

有代码：

CompletePortLogFile::CCompletePortLogFile(string sFullPath)
{
        _sFullPath = sFullPath;
        InitializeCriticalSection(&_freeStackLock);
        InitializeCriticalSection(&_fileLock);
        _hFile = NULL;
        _hCompletePort = NULL;
        _nTotalSize = 0;
        _nPackageNo = 0;
}


if(NULL==g_pLogFile)
{
        g_pLogFile = new IOTP::CCompletePortLogFile(".\\CPPServer.log");
        g_pLogFile->init();
}

核心转储，但我找不到错误位置，有GDB的错误信息
