Title:
  GCC 4.8.4 generates faulty code with -O2 on aarch64

Status in gcc-4.8 package in Ubuntu:
  Invalid

Bug description:
  How to replicate:

  wget http://repo.varnish-cache.org/source/varnish-3.0.7.tar.gz
  tar xf varnish-3.0.7.tar.gz
  cd varnish-3.0.7
  ./configure && make -j 
  make check

  make check fails (as does any use of varnish).
  Same is passing with gcc 4.8.2 or if setting optimization to -O1.
