I have a particular file which when passed to the current fread crashes R. Not reproducible on CRAN 1.10.4 but reproducible on the version at 6019cfb . Very similar files do not have this problem.
The file is a csv (renamed to .txt to upload).
fread('10237-rsession-aborted.txt', verbose = TRUE)
Input contains no \n. Taking this to be a filename to open
NAstrings = [<<NA>>]
None of the NAstrings are numeric (such as '-9999').
`filename` argument given, attempting to open a file with such name
File opened, size 0.000003 GB.
Memory mapping ... ok
Detected eol as \r\n (CRLF) in that order, the Windows standard.
Positioned on line 1 starting: <<row_n,lat,lon,id,place_id,refe>>
Detecting sep ...
sep==','(ascii 44) with 9 lines of 8 fields using quote rule 0
Detected 8 columns on line 1. This line is either column names or first data row (first 30 chars): <<row_n,lat,lon,id,place_id,refe>>
All the fields on line 1 are character fields. Treating as the column names.
Number of sampling jump points = 1 because 2757 bytes from row 1 to eof / (2 * 2757 jump0size) == 0
The text was updated successfully, but these errors were encountered:
Confirming a segfault on current dev: "built 2017-06-03 02:37:39 UTC; travis"
Can add that this works:
fread('head -n 1 ~/Downloads/10237-ression-aborted.txt')
# Empty data.table (0 rows) of 8 cols: row_n,lat,lon,id,place_id,reference...
But even with 2 rows same issue:
fread('head -n 2 ~/Downloads/10237-ression-aborted.txt')
# *** caught segfault ***
# address 0x7fe98f43fa70, cause 'memory not mapped'
Sorry, something went wrong.
