I found out what the problem was, luckily it was just a stupid bug in
my code (an array index out of bounds).
I still didn't quite get how memory allocation works. As far as I
understood there are these two ways of allocating memory:
1. Using malloc/free, new/delete, normal C++ constructors and

Thanks a lot for your help, I'll look at the references. I saw Section
6.1.2 already. Does that mean that I should replace all the calls to
malloc() and to free() with those to Calloc() and Free() in the

Also, see the section in R-exts on debugging compiled code:

gdb can often point you either at, or close to, the code causing the
segfault, which helps to narrow the search.

Without seeing your code, this is a lot like playing 20 questions, but
if your C code is correct, you
might get memory-related segfaults by misunderstanding the lifetime of
the R objects Rcpp references.
