Dear Murray,
I think you might have to update R in first instance and provide a

I believe that this may be more appropriate here in r-devel than in r-help.
The normal hazard function, or reciprocal Mill's Ratio, may be obtained
in R as dnorm(z)/(1 - pnorm(z)) or, better, as dnorm(z)/pnorm(-z) for
small values of z. The latter formula breaks dowm numerically for me
