Hi!

While working on the “reproducible builds” effort [1], we have noticed
that the “buildhash” binary of ispell prints uninitialized memory to a file

The attached patch initializes memory allocated in the parser so all
fields are initialized to a deterministic value (zero).

Once applied, packages using buildhash can be built reproducibly in our
current experimental framework.
