Title:
  ping forgets to whom it's talking

Status in iputils package in Ubuntu:
  Confirmed

Bug description:
  Distro: ubuntu 14.04 x64
  Package: iputils-ping 3:20121221-4ubuntu1.1

  The ping command accidentally uses the information for the last ICMP
  UNREACHABLE response instead of the host from which the *actual*
  response came. See the output below:
