Thanks! Please remove the text above and include the two items below.

# Minimal reproducible example; please be sure to set verbose=TRUE where possible!

  nrow_read <- 1200000
  nrow_skip <- 0
  nrow_df <- nrow_read
  log_fname = "sweep_20230513_1100.log" #attached

  swp_in <- data.table::fread(input = log_fname,
                                header = FALSE,
                                skip = nrow_skip,
                                nrow = nrow_read,
                                verbose = TRUE)

Ty for the report. Your example works on the current dev version. You can update to dev version via data.table::update_dev_pkg()

Is this issue solved? Should be closed?

@MiguelAngelTorres what was missing is a git bisect to know when the issue was fixed for future reference.

Just did a git bisect and this was solved in #5046.
