new/delete mismatch

Dans ma bibliothèque (qui remplace les opérateurs globaux new/delete), j'utilise une autre bibliothèque externe (casablanca pplx). Cette bibliothèque externe n'inclut pas les opérateurs new/delete remplacés (j'ai vérifié en utilisant l'option show includes de Visual studio).new/delete mismatch

Certains objets de cette bibliothèque externe (comme flux ou exceptions) sont créées en utilisant la valeur par défaut new[] opérateur (qui appelle mon opérateur new remplacé) et sont détruits à l'aide de la valeur par défaut delete[] opérateur (qui doesn ne pas appeler mon opérateur delete remplacé). Ceci entraîne une erreur de protection générale .

Qu'est-ce qui peut expliquer ce comportement?

J'utilise Visual Studio 2012.

Exemple code source (google.fr obtenir en utilisant le casablanca client http):

web::http::client::http_client_config config; 
config.set_timeout(std::chrono::seconds(10)); 
utility::string_t uri = L"http://www.google.fr"; 
web::http::client::http_client client(uri, config); 
web::http::http_request request(web::http::methods::GET); 

client.request(request).then([uri](web::http::http_response response) { 
    unsigned short statusCode = response.status_code(); 
    if (statusCode == 200) 
    { 
     concurrency::streams::stringstreambuf stream; 
     return response.body().read_to_end(stream).then([stream](size_t) { 
      std::string responseText = stream.collection(); 
     }); // crash here (stream destructor) 
    } 
});

nouvelles et supprimer les opérateurs:

inline void* operator new (::size_t size); 
inline void operator delete (void* ptr); 
inline void* operator new[] (::size_t size); 
inline void operator delete[] (void* ptr);

Si vous vérifiez la pile d'appel de l'incident, vous pouvez extraire la signature de l'opérateur d'effacement d'exécution. Peut-être n'avez-vous pas écrasé toutes les nouvelles fonctions possibles de suppression/suppression. – geza

Oui j'ai ajouté les callstacks. Et j'ai ajouté les fichiers de nouveaux et supprimer des appels. Je ne comprends pas pourquoi le nouveau personnalisé est appelé, et la suppression personnalisée non. Je suppose que le nouvel op de runtime est compilé dans mon application (dans mon Application64_d.dll), mais pourquoi l'opération de suppression d'exécution n'est pas? –

Avez-vous remplacé 'delete []'? – geza

Dans Visual Studio 2013 (et plus), l'opérateur par défaut delete[] ne se construit pas dans le binaire de l'application (par opposition à la valeur par défaut new, new[] et Opérateurs delete). Il est appelé directement à partir de msvcr110d.dll.

Lorsque le mot-clé en ligne est utilisé, les opérateurs new[] et delete[] remplacés ne sont pas utilisés par défaut dans toute l'application (par opposition aux opérateurs new et delete) à moins que nous inclure explicitement l'en-tête.
L'opérateur par défaut new[](construit dans le binaire de l'application) appelle l'opérateur new remplacé.
Mais le défaut delete[] opérateur (appelé directement à partir msvcr110d.dll) ne trouve pas l'opérateur delete remplacé et utiliser la valeur par défaut delete opérateur (de msvcr110d.dll).

Pour ma solution, j'ai supprimé le mot-clé en ligne et ai placé les opérateurs dans un fichier source.
Ce bogue a été corrigé et ne devrait pas apparaître dans Visual Studio 2015 (et plus récent).
