After some testing, the limit seems to be 64k. It only happens when
reading data that was copied to the clipboard by a Windows program (in
this case Excel).

- Open attached file in Excel
- Ctrl-a to select all, ctrl-c to copy to clipboard
- Then:

582 $ getclip >out.gc

583 $ cat /dev/clipboard >
cat: /dev/clipboard: Bad address

584 $ wc /dev/clipboard
wc: /dev/clipboard: Bad address
    400   13526   65536 /dev/clipboard

585 $ ls -la out*
-rw-r--r--+ 1 jhetzler Domain Users 65536 Jun 14 23:03
-rw-r--r--+ 1 jhetzler Domain Users 73922 Jun 14 23:03 out.gc

This is 1.7.20 on 64-bit Windows 7 and Excel 2013.

Does that help?
