Title:
  OpenCV-3.2: Use of uninitialized variable in polygon drawing

Status in opencv package in Ubuntu:
  New

Bug description:
  Description:    Ubuntu Bionic Beaver (development branch)
  Release:        18.04
  Package:        libopencv-imgproc3.2:amd64 3.2.0+dfsg-4build2

  The OpenCV version frozen in Ubuntu 18.04 has nasty bug where
  uninitialized variables in the guts of drawing of a convex polygon
  runs the output (random horizontal lines), see attached image.

  This thing can ruin sofware perfecly working on OpenCV-2.4 for people
  coming from Xenial to Bionic. See attached image to compare properly
  rendered output and corrupted one.

  This issue has already been fixed in the upstream
  (https://github.com/opencv/opencv/commit/fa36b9d3455d62e98554a996dea3ebf7201109c2).
  It would be worth to integrate the above mentioned patch it the 3.2.0
  package in Bionic.
