上記のコードはGDB情報です。 triagens::basics::Utf8Helper::Utf8Helper()は私のコードと呼ばれていませんでした。私はThirdPartyライブラリから呼び出され、そのメソッドは3rdパーティのソースに存在すると思いますが、utf8Helperキーを検索するときに使用されていません。 私は理由を知らなかったので、助けてくれますか？

Answer 1

@MatthewFisher hm。 doLoadFromCommonDataにブレークポイントを設定しましたが、動作しません。プログラムが参加しませんでした。私は 'export MALLOC_CHECK_ = 2'と './test'を使ってcore.4675を生成します。使用する 'GDB ./test core.4675'、 'どこ' 生産つの通路：

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(); 
} 

は、GDBのエラー情報があります：コードあり
