Fingerprints when using rp_from_buffer are always zero.

[alshalan]

I compiled the code and tried the benchmark example and it worked. I'm getting different fingerprints for different input. I created my own program and tried rp_from_buffer instead of rp_from_stream but unfortunately the fingerprints are always 0.
I used a bunch of printf's for debugging and found that slide8 always call append8 with p=0 and m=0.

Have you tested rp_from_buffer? Any reason why it doesn't work?

Thank you!
