The only thing I can think of: are you keeping track of the number of
bytes, or do you rely on a '\0' as end-of-string? If your data is
binary, you cannot rely on the end-of-string, you have to keep track of
the number of bytes.
Try replacing the bzip2 with 'cat', and then test your code, much easier
for debugging. Start with a simple file with a single character or so.
