[Bug 1388036] Re: qemu-img segmentation fault when asking for options

[Serge Hallyn]

** Description changed:

+ ================================================
+ Impact: qemu-img segfaults
+ Test case: qemu-img convert -O qcow2 -o ? a b
+ Regression potential:  this only ensures that data is initialized before we call a fn dereferencing it. Any regressions will be localized to qemu-img.
+ ================================================
+ 
  When you ask for options for a command on the precise version of qemu-
  img
  
  qemu-img convert -O qcow2 -o ? a b
  
  The tool seg faults:
  
  Supported options:
  size             Virtual disk size
  backing_file     File name of a base image
  backing_fmt      Image format of the base image
  encryption       Encrypt the image
  cluster_size     qcow2 cluster size
  preallocation    Preallocation mode (allowed values: off, metadata)
  Segmentation fault (core dumped)
  
  This is fixed upstream in later versions, but may be worth backporting
  to precise.
