Summary: SFTP resume with 4GB file does not work

Initial Comment:
I was trying to resume a file, part of which was downloaded with scp. The file is ~3.5GB large (3579444861) and the small part is
176521216 bytes. However, curl refuses to resume the file with the message:

curl: (36) Offset (176521216) was beyond file size (-715522435)

command line:
/usr/src/curl-7.21.1/src/curl -v sftp://user@server/backup/file.tar.bz2 -C - -o file.tar.bz2

curl version:
curl 7.21.1 (x86_64-unknown-linux-gnu) libcurl/7.21.1 OpenSSL/1.0.0a zlib/1.2.3 libidn/1.18 libssh2/1.2.5
Protocols: dict file ftp ftps http https imap imaps ldap ldaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp
Features: IDN Largefile NTLM SSL libz

PS: ever worse, if I leave out the '-C -' part, curl crashes :(

Message:
Right, to me this looks like a bad server-end that responds with a weird
file size on the SFTP stat request. I'll soon provide you with a test patch
to allow us to see this in detail.

PS: against another ssh 5.5 it works

Do you know what server software and version is running in the other end?
