It is not the performance optimization that isn't working, but the code
path through plain stdio while doing a diff that was probably never
exercised (the tests all pass on Cygwin).  Try RCS_MEM_LIMIT=0 to force
stdio.  The error does not occur on Linux and it doesn't seem to be
known to the devs.

Achim.
