  if (!is.null(max.nelements) && nelements > max.nelements) {
    title <- sprintf("estimated design matrix size: %.2f GB (%d elements)",
                     nelements * 8 / (1024 ^ 3), nelements)

The %d notation in the above code does not work for the case when nelements is truly big (> 2 ^ 31 - 1).
Use %.0f instead.
