I put some traces in the progress callback along with some timing formation.

lcurlret is 0
upload returned http return code of 500

End do upload

The entire data is never sent across. The data sending stops at 474684 and
does not proceed further.
The connection is closed after a huge amount of time roughly 300 secs or so.

Both windows and mac libcurl versions are 7.19.3 compiled with libssh and
openssl support. The same request are sent and the msgs output by curl when
verbose is set to on are same except for the final http status code which is
200 on windows and 500 on mac.If required i can post the output of
curlopt_verbose when the program is run on windows.
