Re: [pdf-devel] more notes on pdf-stm-f-a85.c

   1.  There is no overflow check (maximum 5-tuple should be 's8W-!', but
   there are more efficient means of checking for an overflow as the
   result is calculated).

Thanks for pointing this out. I will care about it in the new decoder
implementation.

   2.  The memory handling is insufficient; in the current implementation
   it is trivial to overflow the allocated memory - for example, just
   make the input "zzz~>" - a perfectly valid stream.

The old growing-buffers implementation is being replaced.
