You're right!
Thanks to everybody here, and I am sorry for that "non-sense" bug report!

I forgot to put the folowing includes in my last post:

Hi Simon!
You are right!
Ok, here it is (a little resumed):
#include
#include
#include
#include
#include "interface.h"
SEXP main() {
int gtype, inform, m, n, maxoutit, maxtotit, maxtotfc, outiter,
totcgcnt, totfcnt, totgcnt, totiter, iprint, ncomp, i;
double f,nalpsupn,epsfeas,epsopt,snorm;

This .Call without parameters is just for a test. I am constructing an
interface to this C/Fortran optimization package, and because this
segmentation fault pr
that when it tries to use the address as a SEXP.

Hello to everyone!
I use .Call to call a C function without arguments wich calls a
fortran optimization package. My C function uses others C and Fortran
functions and it works fine when I call it from a main() in a C
program. But when I call it from R with
.Call("name_of_the_c_function"), R gives m
