I've already sent this to the help-rcs mail list; but haven't received an
answer. I am resending it here with some additional information.

The example contains one directory, src, with a working file In.cpp, and an
RCS subdirectory containing one rcs archive file In.cpp,v. When the command
ci In.cpp is executed, a message is generated,

file is unchanged; reverting to previous revision 1.7.1.1

following which another message is generated,

Aborted

and an empty file, ",In.cpp,v,", appears in the RCS subdirectory. I haven't
been able to find anything wrong with the In.cpp,v file, and because of
that it is probable that a bug in involved. I note that I have observed a
similar outcome on other occasions (i.e. when attempting to check in an
unchanged file).

Note: Before trying the command "ci In.cpp", the user must execute "rcs
-l1.7.1.1 In.cpp" to break the current lock of revision 1.7.1.1 and create
a new one.
