新しい機能の1つである非同期エージェントライブラリを使用しようとしています。追加しました
unbounded_buffer m_myDataBuffer; 私のC++クラスには、これ以上何もありません。エージェントはまだ実行されていません。
アプリケーションでメモリリーク検出を有効にするために、次を使用しています。
#ifdef _DEBUG
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
#endif
しかし、アプリケーションウィンドウを閉じた後（私は単純なWin 32 GUIアプリケーションを使用しています）、VisualStudioは大量のメモリリークを示しています。

コメントアウトするとすぐにリークがなくなります
unbounded_buffer<int> m_myDataBuffer;
またはコメントアウトした後
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
unbounded_bufferを使用しなくても解放するために、何か特別なことはありますか？または、特別な方法で_CrtSetDbgFlagを設定する必要がありますか？_CrtSetDbgFlagはメモリリークの原因ですか、それともこの場合に何らかの理由で誤った検出を作成していて、実際のメモリリークはありませんか？ここで何が欠けていますか？
私も持っているので、これらのリークは私のコードから来ていないことを100％確信しています
#ifdef _DEBUG
#define _CRTDBG_MAP_ALLOC
#include <stdlib.h>
#include <crtdbg.h>
#define new new(_NORMAL_BLOCK,__FILE__, __LINE__)
stdafx.hにあるので、コードからのメモリリークにはファイル名と行があります。しかし、unbounded_bufferのものにはそのような情報がないので、エージェントライブラリからのものだと思います。
