That's hard to explain; this is not supposed to happen.

One theory is that there is a hardware problem with your computer's
memory (or your hard disk), making it present the byte code
differently in memory than it is on disk. I've also seen file system
drivers stomp on the buffers they read from disk (Linux reiserfs in
particular).

It could be a bug in Python also, but that is unlikely :-)
