I've noticed a similar behavior in other implementations when the last
argument of accept(2), the size of the second argument (struct sockaddr), 
isn't large enough or even exactly of the right size.  Can you tell the
size of the (struct sockaddr_in) on your architecture, compare it to the
value that is passed as last argument to accept(2) in daemon.c, and see if
passing the exact size you can have the "from" filled as expected?
