It's not the most recent recent, but I see the same exact behavior on
fuse 2.6.15, fuse-utils 2.4.2, sshfs 1.3 from Ubuntu Dapper.

For pos=8120, at offset 8192 (0x2000) it reads back all 0's.
For pos=12180, at offset 12288 (0x3000),
for 16380, at 0x4000
for 20440, at 0x5000
... and so on.

So, whenever your buffer crosses a multiple of 0x1000 except for 0x1000
itself, the remainder (the portion of the buffer beyond 0x2000) reads
back as 0s.  Strange.

The on-disk file is fine.  It contains the correct data.  The problem
appears to be in the readback.
