[Rcpp-devel] Rf_error() format string

[Serguei Sokol]

Hi,

I've got a request from CRAN to correct my package rmumps using Rcpp:
https://cran.r-project.org/web/checks/check_results_rmumps.html

The problems come from RcppExports.cpp automatically generated lines like:

    Rf_error(CHAR(rcpp_msgSEXP_gen));

With a message saying:

Found the following significant warnings:
    RcppExports.cpp:58:18: warning: format string is not a string 
literal (potentially insecure) [-Wformat-security]
    ...

The fix may be as trivial as:

   Rf_error("%s", CHAR(rcpp_msgSEXP_gen));

However, if I do it manually, it will be overwritten at the next 
RcppExports.cppbuild.
Are there some plans to incorporate this fix in Rcpp?
Am I alone in this case?

Best,
Serguei.
