Subject: [PATCH] traceroute bus error on sparc

Package: traceroute
Version: 1.4a12-19

  $ traceroute www.debian.org
  traceroute to www.debian.org (194.109.137.218), 30 hops max, 38 byte packets
  Bus error

The fault occurs in send_probe, at:

    memcpy(&outdata->tv, tp, sizeof(outdata->tv));

seems to be an alignment problem; removing __attribute__((packed)) from
the tv element of outdata fixes the problem.
