Summary: curl_easy_perform not working cross platform

Initial Comment:
Hi. Using libcurl v 7.20, Windows 7 and Ubuntu 9

I create a file using standard fopen(), fwrite(), fflush(), fclose() and then copy to my web server,

I have a client that uses libcurl and curl_easy_perform() to download the file. This is where I get the mixed results.

When I create the file on a Windows machine, only the Windows client can pass my integrity check on the downloaded file (decrypt file, check valid signature), Fails on Linux.

And when i create the file on Linux, only the Linux client can pass. Fails on Windows.

I did a dump of the downloaded file's buffer and its exactly the same except the end of the buffer. It seems that at the end of the buffer on Linux there is a 0. But when done on Windows, there is an extra couple bytes at the end (presumably the EOF character?). And I do put the '\0' at the end before exiting the callback function.

I can't provide the URL or source code, but its very standard and simple, nothing special. Uses CURL_OPT_WRITEFUNCTION to write the data to a buffer in a callback function.

Any advice? Anyone seen anything like this before? If not I will assume its something with my reading/writing files.

Please let me know. Thanks
