fread on particular file crashes R

[cnoelke]

Looks very similar to #2167, I have a file that crashes R if read with fread. Very similar files do not have this problem. read.csv works fine with this file.

The file is a csv (renamed to .txt to upload).

df <- read.csv("session_aborted_fatal_error.txt", header=F)
dt <- fread("session_aborted_fatal_error.txt", header=F, verbose = TRUE)

Thanks!

please run this from the command line to get a tad more feedback about how R crashed

Sorry, is this better?

no, this:

library(data.table)

fread('~/Downloads/session_aborted_fatal_error.txt')

Sorry, not sure what you mean. I'm running this on Windows RStudio. I can run the script from the Windows command line, but the output is identical to what RStudio produces.

Thanks!

This looks like an instance of #2194
A fix already exists, waiting to be merged.

Many thanks @cnoelke. Your file now added to the test suite.

I have the same problem with loading one particular file with fread().

Here is the error file: session_aborted_fatal_error.txt

Hello,

It has been awhile since this closed, but I am facing the same issue on R version 4.1.0 (2021-05-18)
I could isolate the issue.

RStudio crashes if you try to read row 183131
DT <- fread(file = "file.csv", sep = ";", fill = T, verbose = T, nrows = 183130)

file.zip

If it is not the same file then I think it make sense to file a new issue
