GetRNGstate() crashes with 'Segmentation fault'
Whyever do you think that should work? If you want to link against libR.so and call into R, you do need to initialize R, and you have not done so. I also don't see that the program has any use. The complicated ways to manipulate the random number generator are really only of any use from R code (via C code, perhaps).

Dear R-masters,
I tried to compile this simpel C-code:
//-----------------
#include<R.h>
int main()
{
GetRNGstate();
return 0;
}

Where am I wrong?
I'm using R 1.6.1, glibc-2.3.1 on Debian woody system.
Thanks a lot!
