gcc (4.8.3) options de désinfection pour les fonctions de liste noire

Question

Je compile mon code sur gcc 4.8.3. J'ai activé l'option -fsanitize=address. Mais mon programme se termine au démarrage en lançant une erreur globale de dépassement de tampon dans le code de la bibliothèque tierce. Donc, j'essaie d'ignorer le désinfectant pour cette fonction (ou la fonction de l'appelant). J'ai essayé __attribute__((no_sanitize("address"))) mais le compilateur lance l'avertissement que ‘no_sanitize’ attribute directive ignored a même essayé -fsanitize-recover=address mais la récupération ne semble pas être prise en charge sur l'adresse. Quelqu'un peut-il m'aider avec comment faire pour que mon programme continue après la première erreur, ou la fonction de liste noire pour sauter l'aseptisation?

EDIT

template <class T> 
void __attribute__((no_sanitize_address)) OID_CB<T>::Init(s8_t* name, s8_t* data, u32_t entryNum, u32_t start, u32_t end, u32_t entrySize, bool ViewFlag, bool WholeTableFlag) 
{ 
     strcpy(mName,name); 
     mName[strlen(name)]='\0'; 
     mData   = data; 
     mEntryNum  = entryNum; 
     mStart  = start; 
     mEnd   = end; 
     mEntrySize = entrySize; 
     mIsView  = ViewFlag; 
     mIsWholeTable = WholeTableFlag; 
}

J'ai essayé attribut ((no_sanitize ("adresse"))) mais le compilateur jette avertissement que 'no_sanitize' attribut de directive

I J'ai peur que GCC ne supporte pas cette syntaxe (il y a même a bug in their Bugzilla). Vous devriez être capable d'utiliser no_sanitize_address cependant (lisez à ce sujet dans docs).

même essayé -fsanitize-recover = adresse mais la récupération ne semble pas être pris en charge sur l'adresse.

Cela ne est apparu dans GCC 6.
