It's not a bug, it's a buffer size choice made with the rcs 5.8 release, 
which affects Cygwin for reasons unknown.

GNU rcs 5.9.2 changed this functionality again in a way which may fix 
the problem:

2013-10-20  Thien-Thi Nguyen  <XXX@XXX.org>

     Relax RCS_MEM_LIMIT default; fall back if unspecified.

     * doc/rcs.texi (Environment): Update ‘RCS_MEM_LIMIT’ description;
     add a willful ignorance hint and speculation on its removal.

I built 5.9.2 under Cygwin with default build options, and it 
successfully runs a test script that fails under the current Cygwin rcs, 
which was posted by Don Hatch when this problem came up here 6 months 
ago: http://cygwin.com/ml/cygwin/2013-10/msg00086.html

Dr Volker Zell, the maintainer of the Cygwin rcs package, did not 
respond to that thread.  A search shows only two emails from him to this 
list since that time.

As far as I know, no one has investigated the reason why this change 
causes a problem on Cygwin, but it would seem that replacing 5.8.2 with 
5.9.2 would help.
