Is the code in question correctly initialising the variable that
the `addrlen' parameter points to before calling accept? It looks
as if this might be the problem in the PR you mention. I mean that
the code should look like
sin_len = sizeof(sin);
s = accept(servsock, (struct sockaddr *)&sin, &sin_len);
where `sin_len' is reset to the correct length before calling
accept() each time. I think sin_len may be reset to 0 when an error
occurs, but otherwise you would get away with not resetting it.
