This is what blocks tcpreplay to migrate to Debian testing, see https://bugs.debian.org/1009199

At first, sorry for not bringing this here earlier. I recall I already had analyzed the situation but as there is no bug report here, I must assume I never sent it, too bad.

    Bug #695 remove FORCE_ALIGN
