Hi,

I'm using Version 7.10.3 release of curl and MSVC6/Win32.

I am getting a CURLE_PARTIAL_FILE error code where I don't expect it.
The attached file is a distillation of a C++ program I'm working on. At
line 89 of my attached test.c, I get CURLE_PARTIAL_FILE as a return
code from curl_easy_perform. It looks as if curl retains the file size
from the previous transfer, then at line 609 of lib\ftp.c executes the
following code:

     if((-1 != conn->size) && (conn->size != *ftp->bytecountp) &&
        (conn->maxdownload != *ftp->bytecountp)) {
       failf(data, "Received only partial file: %d bytes",
*ftp->bytecountp);
       return CURLE_PARTIAL_FILE;

conn->size is non-zero, but *ftp->bytecountp is zero, so the code
returns CURLE_PARTIAL_FILE.

I wonder whether I'm misusing libcurl, or whether the conn->size should
have been reset by curl code while executing my last curl_easy_perform.
If the latter, I'd appreciate some hints as to where I might reset
conn->size.
