Bug description:
  (reported upstream http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59142)

  This is on an ARM platform with Ubuntu/Linaro 13.10 with:

    g++-4.8:
      Installed: 4.8.1-10ubuntu8

  While building OpenCV 2.4.7 with:

    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/home/jm/fidelio/3rd-party/opencv/2.4.7/linaro ..
    make

  I got:
