Might be a bug in R, the package (i.e. Fortran code) or even with your
hardware (CPU temperature).
Hence I suggest to try again with a *recent* version of R (i.e. R-2.8.0)
and a recent version of the package. It would also be nice if you can
make it better reproducible (I haven't seen it during some quick tries).
