That sequence destroys the Deque when it is nonempty.
Since, as stated in the specification, destroyD() must

  // Destroy the Deque *D by freeing any storage that it uses (but not the
  //   blocks of storage to which the string pointers point) and set the value
  //   of *D to NULL.
   
the storage for the line still stored in the Deque is
NOT freed, and valgrind will report it as still in use.

If that is the ONLY such storage reported, then you do
not need to fix the problem.
