[R] loess.smooth dumps core

Has the loess.smooth() function changed? It used to work, but now it causes R
to abort with a segmentation fault. I stole the function points.lines() from
V&R 1st ed. pp. 67--68, but now it only works if I remove the line with
loess.smooth. Here's the function I'm using:

points.lines <- function(x, y, ...)
    cor1 <-round(cor(x, y, use="pairwise"), digits=2)
    ok <- !(is.na(x) | is.na(y))
    points(x, y, ...)
    lines(loess.smooth(x=x[ok], y=y[ok]), col=3)
    abline(coef=c(0, 1))
    text(min(x, na.rm=T), max(y, na.rm=T), cor1)

Is this a bug?
