In config_getoverflowstring():

     /* First lookup <ident>_key, to see if we have a service-specific
      * override */

     if (config_ident) {
         if (snprintf(buf,sizeof(buf),"%s_%s",config_ident,key) == -1)
             fatal("key too long in config_getoverflowstring", EC_TEMPFAIL);

         ret = hash_lookup(buf, &confighash);
