Well, the large file offset stuff in smbclient seems to work

There may not be a problem in your client.
But problems may show up in file systems and the support C library
calls. In older systems, bits were precious, so there may be many
fields that do not have enough, and now backwards compatability may be
showing it's age. Sometimes it is found in a device driver that because
at the time a 1GB disk was unimaginable, that the bits above there were
used for flags.
Some algorithms are sound but do not scale well, hence the unexplained
Every 4 bit nybble barrier can be an issue, and the signed/unsigned
usage may also be an issue. The granualarity of blocks in the file system.
Once you get past 4GB, I would expect the next hiccup may be at the 1TB
level and then every power of 2 beyond that.
How many people are dealing with files larger than 4G on a regular basis?
You can not test every thing though. :-)
