segfault with read_fwf() and fwf_positions()

[MatthieuStigler]

I get a segfault error when running the code below, tested on two different Ubuntu machines. vroom (1.6.5) and readr (2.1.5) seem to be at the latest version currently available.

library(readr)
packageVersion("readr")
packageVersion("vroom")
starts <- c(0, 13, 19, 26)
ends <- c(11, 17, 24, NA)


txt <- "ID           Arch  Saved  What
C014KLCJSHY  -     -      #string
C014QHAKJHY  -     -      #somethin"
cat(txt)

channel_ids <- read_fwf(
  file=  txt,
  col_positions = fwf_positions(starts, ends))

Will give:
