fix memory leak in Rcpp::warning under tryCatch handlers (#1475)
The variadic Rcpp::warning() template formatted its message into a
std::string whose destructor would be skipped if Rf_warning() longjmp-ed
(e.g. via tryCatch(warning=...)), leaking the heap buffer. Copy the
formatted message into a stack buffer and let the std::string be
destroyed before Rf_warning() is called.
Closes #1474.1 parent 1b1dcc5 commit d582dd4
