There is too little information here: please use bug.report() to submit bug
reports, and give the exact code you used so we can try exactly the same
thing. A good quick test is to run



x <- ts(rnorm(200))

also works on all my (0.90.1 from a later message) systems, so I suggest
you re-build and re-install R, and run make check as that will run the acf
