Bug description:
  [Impact]

  Parted is crashing (core dumping) during resize operation, while
  changing the end position of a partition.

  [Test Case]

  root@ubuntu-focal:~# parted /dev/sda resizepart 1 100%
  Warning: Partition /dev/sda1 is being used. Are you sure you want to continue?
  Yes/No? yes
  End?  [42.9GB]?
  free(): invalid pointer
  Aborted (core dumped)

  [Where problems could occur]

  As per resize documentation:
  "Note that this does not modify any filesystem present in the partition."
  "When growing a partition you will want to grow the filesystem afterwards"

  FS-wise the resize operation won't try to take action on the FS
  itself. It would need to be done by the admin as a separate step.

  If any problem arise, it will be limited to the resize functionality
  of parted. In this case, the impact would be ~ similar to the actual
  parted state (before this SRU), and one won't be able to resize as
  requested.
