在MAC OSX的同一R会话中调用两个.Call（Rcpp）函数

Question

I am facing a strange problem. The program works fine on a linux machine but on a MAC OSX. The R program crashes. I have 2 R functions. They call two different C++ functions as follows. I call these R functions from a third R function. While using a mac the results from the first .call(main1)function are generated and when the other .call(main2) is called the program crashes saying input parameters not found. When I run them the two functions independently in in separate R sessions they work fine. I just can't figure out the exception. It works fine on a linux machine

> getResults()
{
   funct1() {
       .call(main1, s1, s2)
   }
   funct2() {
       .call(main2, s1, s2)
   }
}

This not a reproducible example so we cannot offer specifics. Can you provide a full example exhibiting your issue?

In general, you can do any one of

• use 'Rcpp attributes' and sourceCpp() and just declare your two functions
• call cppFunction() twice, or cxxfunction() from the inline package
• write a package
