While I am very glad that your problem is solved, I have to say that this makes little sense. If your package does not use Rcpp, it would have to depend on it. But if you don't use Rcpp, you can't trigger the bug you reported. So may another package [ if you use one ] may be buggy and not depend on Rcpp. Impossible to say though from your incomplete report.
