/MDdの代わりに/MTdを使用するように変更したソリューションには、多数のライブラリとプロジェクトがあります。VS2008を使用しています。

/MDdスイッチには存在しなかった大量のメモリリークが突然発生します。

Visual Leak Detectorを使用して、すべてのリークがCRT、VSライブラリ、ブーストなどのさまざまなライブラリの内部にあることに気付きました。

たとえば、ここでは最初の3つのリークのコールスタック（プロジェクトはBoost :: Testプロジェクトです）：

誰かが何が起こっているのか知っていますか？

編集：
私が理解していることから、2つのスイッチ/モードの違いは、2つのリンクされたDLLが同じCRT（メモリ管理など）を共有するか、それぞれが独自のものを持っているかどうかです。それぞれが独自の（/ MT [d]）を使用する場合、一方が他方によって割り当てられたリソースを解放することはできません。
ただし、すべてを静的にリンクしているため、少なくとも私のコードにはDLLは含まれていません。
