Given that R runs many, many other things without doing this, it is almost 
certainly a bug in one of those packages. The way to find the original 
problem is to run under valgrind (possibly using an R build set up for 
it): the report is probably on a result of previous memory corruption.

See 'Writing R Extensions' for how to debug such issues.
