Rsync 3.1.3 segfault

[Marcin Krol]

Hello.

I've problem with rsync 3.1.3 in my distribution (TLD Linux). It 
segfaults when service is started. Services are controlled by rc-scripts 
(TLD Linux is systemd free). Actual command thats being run by 
rc-scripts is:

nice -n 15 initlog -c "/usr/bin/rsync --daemon 
--dparam=pidfile=/var/run/rsync.pid"

When ran by hand it works, when ran from rc-scripts rsync segfaults. The 
only difference is that rc-scripts are closing/redirecting std streams 
prior to calling above command.

The code responsible for segfault is new popt_unalias function added in 
3.1.3. To be exact this line causes segfault:

poptAddAlias(con, unalias, 0);

When commented out everything works.

Workaround for now to get it running is to comment out popt_unalias calls.

I'm hoping for little help to nail down what exactly causes segfault and 
fix it :-)

Cheers
Marcin
