Sure.  It would indeed solve the visible problem, but not what happens
below the iceberg.

By the way, if I change
    memset( &new->Address, 0, sizeof( new->Address ) );
    memset( &new->Address, 1, sizeof( new->Address ) );
or another value, "localhost" is not written;  I thought ss_family
could be AF_INET or AF_INET6 (or 0).

Sorry for this lame question but... how to run innd under valgrind?

I tried

    valgrind --trace-children=yes --track-fds=yes --log-file=inn-valgrind /home/news/bin/innd

(and also
but it does not work.  After a few seconds, valgrind stops...  (And innd goes on alone.)
