Hello everybody,
I just ran into the following problem: Using Rcpp::wrap with a NULL pointer
crashes my R. I'm not so sure if this is a bug or if I'm using Rcpp::wrap in a
way it shouldn't be used, so I wanted to discuss this here.
Here is some example code:
This works fine:
#-----------------------------------
library(inline)
src <- '
const char* ret = "test";
return Rcpp::wrap(ret);
'
fun <- cxxfunction(signature(), src, plugin="Rcpp")
fun()
#-----------------------------------
Whereas this crashes R:
#-----------------------------------
src <- '
const char* ret = NULL;
return Rcpp::wrap(ret);
'
fun <- cxxfunction(signature(), src, plugin="Rcpp")
fun()
#-----------------------------------
I'm using Rcpp 0.9.4 and R.2.13, which I think are the latest versions.
Regards,
Christoph
PD: Dirk, Romain, I just read through the slides you made for this workshop a
month ago. Great work! Thanks a lot!
