Description of problem: Modules/socketmodule.c contains: #ifdef ENABLE_IPV6 char ip[MAX(INET_ADDRSTRLEN, INET6_ADDRSTRLEN) + 1]; #else char ip[INET_ADDRSTRLEN + 1]; #endif ... /* Guarantee NUL-termination for PyString_FromString() below */ memset((void *) &ip[0], '\0', sizeof(ip) + 1); which overwrites the ip[] buffer by 1 byte.
