This looks like for some reason the buffer holding the input data is longer
than it should be. I can't tell from this why that would be. Are you able to
reproduce this using a complete test case that I can try compiling?

A couple of questions to check:

Q. Is the data being sent as multipart/form-data?
Q. Does the post data buffer on the request have these extra characters too?
You can get hold of the complete post data buffer by looking at
request::post_data() - note that it is a vector<char> so you can't stream it
to cout directly!

Let me know how you get on.

Cheers,
