The writer.write_all() call accessed data marked as
undefined to valgrind. Note that we shouldn't write out
uninitialized memory for security reasons anyway.
(note that vec::undefined already did zero-initialize the
data, but also marked it as undefined for valgrind when
compiling with the valgrind feature)
