Now I have.  The computer is my laptop and not connected to the net
so I can't upload details, but R-1.2.1-patched as of yesterday does
NOT exhibit the same bug.  So I guess you are right.  Sorry for wasting
your time.  I'm still a newbie at this R stuff.  Next time I'll check
against R-*-patched before submitting a bug report.
