This bug requires CURLOPT_COPYPOSTFIELDS and curl_easy_duphandle() to be used in that order, and then the duplicate handle must be used to perform the HTTP POST. The curl command line tool is not affected by this problem as it does not use this sequence.

For Debian 6 Squeeze, these issues have been fixed in curl version 7.21.0-2.1+squeeze10");
