[R] does segfault mean (always) a bug?

In R, a segfault always indicates a bug.  What's not so clear is whether
it is a bug in R, a bug in a contributed package, or a bug in some
underlying system library.

If you can only trigger the bug when using a Bioconductor package, then
the first guess is that it is that package, and the maintainer of that
package is in the best position to track it down further.  If you can
simplify the code to trigger it without using any contributed packages,
then it could well be a bug in R, and we'd like to see code to reproduce it.
