>          Components: Core, SSL
>            Reporter: Brian Geffon

> We've observed a bug in a production environment where clients would receive malformed NPN sets. This is caused by a race condition in SSLNextProtocolSet::advertiseProtocols:
> {code}
>  if (!npn && !this->endpoints.empty()) {    
>    create_npn_advertisement(this->endpoints, &npn, &npnsz);
>  }
> {code}
> Obviously this code is attempting to initailize the npn offer string on the first SSL request to that port, this is a race condition. I have a fix that will be committed today.
