I have used rmail a lot and generally have found it to be pretty
reliable.  One small bug has been popping up pretty regularly,
however:

When I say "M-x rmail" to read new mail, I sometimes get a message
that says "File has changed since last visited or saved.  Read from
disk? (yes or no) ".  I usually say yes, because I am a little worried
that I may overwrite and lose some incoming mail if I don't.  No
matter what I say, though, I usually get another error right away that
says "Invalid search bound (wrong side of point)" and rmail gets
screwed up.  Instead of displaying only the current message, I see the
"raw" RMAIL file in my RMAIL buffer with all sorts of control
characters and header information and the normal rmail commands don't
work.  

Of course, this only happens when I invoke the rmail function after
the RMAIL buffer already exists.  I can get around it by just killing
the buffer and re-executing the rmail command, but I get a little
nervous about the possibility of losing incoming mail.

Why would the RMAIL file get changed?  Perhaps GNU somehow gets messed
up and loses track of the correct last-save-date for the RMAIL buffer.
I can't really think of anything else that could be happening.  My
RMAIL file is protected.  Does anyone know what is going on here?

By the way, this happens to other users on my machine, as well.  It's
GNU 18.37.1 on a Sun 3/75.  

Thanks,
