Does Rcpp::stop() require an extra unprotect?

Question

When terminating early with Rcpp::stop(), is it necessary to unprotect early in the below example?

I'm aware that I could have rewritten this using IntegerVector without the protect and unprotect calls, but I suppose I'm asking this for my own understanding as the function produces no stack imbalance warning with or without the first UNPROTECT.

library(Rcpp)
cppFunction('SEXP with_protect(){
          SEXP out = PROTECT(Rf_allocVector(INTSXP, 10));
          int *p_out = INTEGER(out);
          if (true){
          UNPROTECT(1);
          Rcpp::stop("early termination");
          }
          p_out[0] = 10;
          UNPROTECT(1);
          return out;
          }')
cppFunction('SEXP without_protect(){
          SEXP out = PROTECT(Rf_allocVector(INTSXP, 10));
          int *p_out = INTEGER(out);
          if (true){
          Rcpp::stop("early termination");
          }
          UNPROTECT(1);
          return out;
          }')
with_protect()
#> Error in eval(expr, envir, enclos): early termination
without_protect()
#> Error in eval(expr, envir, enclos): early termination
