exception dans un string

Hello, dans le cadre du développement d'un serveur jeu j'utilise un serveur open-source nommé MaNGOS (http://getmangos.com/), avec sont client ( http://www.mangosclient.org/).

Sauf que voila, le programme serveur en question s'arrête suite a une exception que je n'arrive pas a résoudre. J'ai un backtrace réaliser avec GDB. L'exception se produit très aléatoirement, la fonction peut se produire des milliers de fois sans erreur, c'est d'ailleurs sa que je ne comprend pas.

backtrace :

L'erreur se produirais quand un string se crée ? vraiment étrange.

Tokens StrSplit(const std::string &src, const std::string &sep)
{
    Tokens r;
    std::string s;
    for (std::string::const_iterator i = src.begin(); i != src.end(); i++)
    {
        if (sep.find(*i) != std::string::npos)
        {

            s = "";

            s += *i;
        }
    }
    if (s.length()) r.push_back(s);
    return r;
}

Voila voila, si quelqu'un pouvez se pencher sur mon probleme je lui serais très reconnaissant, car je ne vois pas en quoi la création d'un string pourrais faire cela Oo.
