Re-merged patch by Robert Scheck <robert@fedoraproject.org> for tcpick <= 0.2.1,
which fixes a double-free error detected by glibc on runtime during the execute of
commands like "tcpick -wu -p -i eth0" causing a infinite loop after recording some
sessions. The patch is originally from Cédric Delfosse <cedric@debian.org>.
