I'm experiencing .Call issues when running functions built with Rcpp on Windows, if my c++ code uses C++11 std::regex and I have found no way out so far.

Issues only arise after packaging, not using Rcpp::source("test.cpp")
.Call issues arise as soon as a regex is declared in the C++ code. Using it or no (as in std::regex_match) makes no change.

Unlike prior questions on similar issues, I have had neither building nor linking issues. Rcpp packages build and link fine using the C++11 plugin, making usable packages on my platform. C++11-specific constexpr declarations and functions like std::stoi cause no issue when std::regex is not used.

The same packages build, install and run fine under linux, using vanilla std::regex.

Windows platform is :

R version 3.2.3 (2015-12-10)   
x86_64-w64-mingw32/x64 (64-bit)   

Running under:

Windows >= 8 x64 (build 9200)  
Rcpp_0.12.3   
Rtools 3.3.0.1959 running g++ 4.9.3 (x86_64-posix-seh, 
built by MinGW-W64 project), normally C++11-compatible.  
PKG_CXXFLAGS="-std=c++11"

Attached is a code chunk for testing.

test.cpp.txt

This code runs OK when built using -DNO_REG. Otherwise invoking test::my_test(1, "1000") returns:

  `Error in .Call("test_my_test", PACKAGE = "test", prop, index) : 
      "test_my_test" not available for .Call() for package "test"`   

Packaging code:
R console:

     Rcpp::Rcpp.package.skeleton("test", attributes=TRUE, example_code=FALSE, cpp_files="test.cpp")     
     Rcpp::compileAttributes("test")   

CMD console:

     REM paths to R/bin/x64 and Rtools/bin, Rtools/mingw_64/bin added to PATH         
     set PKG_CXXFLAGS=-std=c++11      
     R CMD build test    
     R CMD INSTALL test_1.0.tar.gz
