does segfault mean (always) a bug?

hi eveybody I'm trying something simple (Biocunductor packages), so simple I believe it's example from docs but I get segfault. I don't suppose incorrect scripting can cause segfault, right?
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. Duncan Murdoch
hi Duncan I remember that this was a principle of most of programming languages, only a bug in the code and/or compiler could cause segfault. In my case it is a contributed package, specifically GOSim package, I'm not R programmer and I realise my scripting is far from good and possibly with errors. I could send that snippet of the code here if people think it can be looked into and segfault could be replicated? I also emailed the author. many thanks P.
