I don't know what caused the corruption, but it's a systematic error.
Throughout the patch, the dereference symbol -> has been changed to
-& so it's not surprising that the patch won't apply.  I've never seen
that particular problem before.

I don't think the line numbers (e.g.532) are responsible.
