Are you on a Windows platform of some kind (I guess so, from your mail
headers)? I vaguely remember having a problem like this (in Python,
IIRC) because MSDOS used ^Z (ASCII 26) as an end of file marker. So
low-level Win32 file access routines still interpret this character as
end-of-file. I got round the problem at the time by using binary i/o.
I don't know whether this is possible in Haskell.
