[Rcpp-devel] unloading/reloading Rcpp based custom package crashes my R session

[Anwar Ludin]

Hi Dirk,

Yes I noticed that RStudio was restarting the session whenever you 
rebuild the package. I guess RStudio does this in order to make sure 
that the session is clean. I am however a bit worried from an RStudio 
end-user's perspective because the package can be loaded/unloaded using 
the package selection functionality in RStudio,  and whenever the user 
does that the R session crashes.

Regards,

Anwar
