[Rcpp-devel] Rcpp::sourceCpp Problem with R 4.3 update

[Dominick Samperi]

Looks like the recent update to R 4.3 broke Rcpp::sourceCpp.

Here is a simple example...

library(Rcpp)
Rcpp::sourceCpp(code='
  #include <Rcpp.h>
  using namespace Rcpp;
  // [[Rcpp::export()]]
  SEXP cpptest(NumericVector v) {
    return v;
  }'
)
cpptest(1:5)

This works without problems under R 4.2.3, but under R 4.3 I get...

using C++ compiler: 'G__~1.EXE (GCC) 12.2.0'
C:\rtools43\x86_64-w64-mingw32.static.posix\bin/ld.exe: internal error:
