[The problem is that 1.34.54.1 appears only in the deltas (in the
terminology of rcsfile(5)), not the deltatexts.

CVS's behavior reading the file is similar to RCS's:
    $ cvs co -r 1.34 usecases.tei
    U ./usecases.tei
    $ cvs co -r 1.34.54.1 usecases.tei
    cvs [checkout aborted]: unexpected EOF reading RCS file /home/kingdon/tmp/root/usecases.tei,v

The question is how the RCS file got to be that way.  Presumably a CVS
bug but will require more investigation to try to track down how to
reproduce this or what would have caused it.  Doesn't look like
operating system/hardware/&c flakiness given what is wrong/right with
the file.

Do note that the file contains characters with the eighth bit set so
this could be related to the 1998-12-23 fix to src/*.c involving
ctype.h calls (this is unconfirmed, I haven't thought much about
whether it could explain this symptom).

I've mirrored the ,v file at http://www.cyclic.com/cvs/dev-eof-v.txt

Hi!

I'm getting this kind of errors time to time.  That's what happened just
now:

retrieving revision 1.34.54.1
cvs [update aborted]: unexpected EOF reading RCS file /usr/local/src/cvsroot/akhavr/casino/doc/usecases.tei,v

$ cvs --version
