Yes, as I posted yesterday:

  Suppose that stdin contains one character, and that
  encode is running in Stage 3 and has assigned a code to
  the empty string.  Then encode will call putBits() to
  write one 9-bit code to stdout.  putBits() can only
  output the high-order 8 bits of this code and thus must
  save the low-order bit for the next call.  But unless
  encode calls flushBits() (or does something equivalent),
  there will not be a next call and the low-order bit will
  never be output.
