I mean: after the Rf_initEmbeddedR is called?

I Objective Caml is really static. Which means that if I declare R.null 
to be R_NilValue, it will take the value of the pointer before 
Rf_initEmbeddedR is executed. And it would be garbage. That would 
perhaps be my issue.

Could someone confirm?

All the best,
