I am forwarding this to freebsd-bugs as it is also FreeBSD related (well at
least
I mentioned FreeBSD) and I am unsure if the rcs-bugs mailing list is active
because
I have got no acknowledgement since I originally posted to it.

Subject: co does not lock third verion if two versions already locked by
same user.
I believe we have found a serious bug (or an undocumented feature in RCS
5.7).
I have just installed RCS verion 5.7 on our DEC Alpha and IBM RS6000
machines.
Installed from source code downloaded from GNU master site, compiled with
vendor
supplied C compilers under DEC OSF1 V3.2 and IBM AIX 4.1. I also
reproduced the
same problem under FreeBSD 2.2.8 using the supplied RCS version 5.7
binaries from
Walnut Creek CD-ROM.
We find the following steps reproduce the problem on all the specified
environments:
1. Create three versions of file test.c: versions 1.1, 2.1 and 3.1.
2. A user checks out two of of the versions with locks using the following
commands:
co -l1 test.c
co -l2 test.c
Result: RCS successfully checks out and locks versions 1.1 and 2.1 of file
test.c.
3. The same user then attempts to check out and lock version 3.1 with
command
co -l3 test.c
Here is the result:
(david@rs6k)$co -l3 test.c
test.c,v --> test.c
co: test.c,v: multiple revisions locked by david; please specify one
revision 3.1 (locked)
writable test.c exists; remove it? [ny](n): y
co: test.c,v: warning: You now have 3 locks.
done
(david@rs6k)$rlog test.c
RCS file: test.c,v
Working file: test.c
head: 3.1

4. I believe that the co command should have allowed the user to check out
version
3.1 of file test.c - this was the behaviour observed with our previous RCS
software
(version and source unknown - maybe version 5.5).
Notes:
1. The error does not occur if a different user checks out the file (with a
lock).
2. The user can lock the file with command "rcs -l3 test.c" and then check
out
the file with command "co -r3 test.c".
