Cheers for the follow up Gregor,
I was following advice given by Prof. Ripley in a posting on R-Help
about how to get the per mille character:
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/48709.html
It should look like a "%" character but with two circles at the bottom.
I get the same (stack smashing) behaviour on my FC5 laptop with R 2.3.1
patched as below:
