I've downloaded this, and it complies and runs seemingly fine, but
FWIW, I think you did misread the spec.

Going by the example parsing code in section 23.3.6, not by the BNF
itself (but that seems to agree), it says (shortening it a bit):

       read chunk-size and CRLF
       while (chunk-size > 0) {
          read chunk-data and CRLF
          read chunk-size and CRLF

The server doesn't appear to send the CRLF after chunk-data. It goes
straight from the data to the next chunk-size. Hmm. Of course, I could
be wrong. Happens often enough.
