I modified code as below:
if (attrs->flags & LIBSSH2_SFTP_ATTR_SIZE) {
        attrs->filesize = _libssh2_ntohu64(s);
        s += 8;
    }
    else {
        attrs->filesize = 6; //test file length
    }

It can download file correctly.

Found that, in libssh2\src\sftp.c function sftp_bin2attr(), the data do not have LIBSSH2_SFTP_ATTR_SIZE and LIBSSH2_SFTP_ATTR_UIDGID flags,
but when listing files, it can get file size (have LIBSSH2_SFTP_ATTR_SIZE flag).
 
Test with FileZilla client, maybe it also cannot get UID/GID (the UID and GID are "0"), but can dload file correctly.
Why libssh2 cannot get file size when try to download files?

I know someone else get the similar issue, http://curl.haxx.se/mail/lib-2012-06/0156.html,
Can get this file correctly by FileZilla client.
Is there any update for this issue?

Thanks!
