Status in QEMU:
  Fix Released

Bug description:
  Head is at 3d7196d43bfe12efe98568cb60057e273652b99b

  Steps to re-produce:
  1. git clone
  ./configure --enable-gcov --target-list=ppc64-softmmu
  make
  cd tests/qemu-iotests

  2. export qemu binary, in my environment
  export QEMU_PROG=/home/nasastry/qemu_gcov/ppc64-softmmu/qemu-system-ppc64

  3. Run test 58 with format qcow2
  ./check -qcow2 58
