n_max = 0 / col_names: crashes R when reading from a remote connection

[ramiromagno]

Hello fellow developers,

• Source file: https://www.informatics.jax.org/downloads/reports/MRK_List2.rpt
• vroom version: 1.6.5

Here is a cute bug:

col_names <-
  c(
    "marker_id",
    "chromosome",
    "genetic_map_pos",
    "start",
    "end",
    "strand",
    "marker_symbol",
    "marker_status",
    "marker_name",
    "marker_type",
    "feature_type",
    "synonyms"
  )

# Works fine from local file
vroom::vroom(
  file = "~/dwl/mgi/MRK_List2.rpt",
  col_names = col_names,
  n_max = 0
)

# Does not work from remote connection: crashes R.
vroom::vroom(
  file = "https://www.informatics.jax.org/downloads/reports/MRK_List2.rpt",
  col_names = col_names,
  n_max = 0
)
