Sorry for the repeated post (in 2 different mailing lists). Tnx for your suggestion. Now I think I've found the problem. Try this: ////file foo.c
#include <R.h>
int **box;
void foo(){
  int i;
  box = (int**)R_alloc(1, sizeof(int *)); }
Compiled with R CMD SHLIB foo.c
In R:

*Segmentation fault*
The problem disappears when the declaration of 'box' comes inside the function foo... Is this a bug?
