[datatable-help] fread crash

[Arunkumar Srinivasan]

statquant,

Thanks for reporting. One useful thing would be to do:

options(data table.verbose=TRUE)
and copy/paste the messages displayed as well. If you can reproduce it with a small file (like you seem to have), maybe you can also attach it (here or on the bugs page, once it's clear it's a bug)?

I got the following crash message using fread 

R) data <- fread(FILE) 

*** caught segfault *** 
address 0x2acf7d5000, cause 'memory not mapped' 

Traceback: 
1: fread(FILE) 

Possible actions: 
1: abort (with core dump, if enabled) 
2: normal R exit 
3: exit R without saving workspace 
4: exit R saving workspace 

FYI: 
R version 3.0.1 (2013-05-16) -- "Good Sport" 
Copyright (C) 2013 The R Foundation for Statistical Computing 
Platform: x86_64-unknown-linux-gnu (64-bit) 

That's probably due to the file itself, the csv file is generated by kdb, 
head/tail looks ok though 
fread(FILE,nrows=5) crashes too 

What can I do to trace back the issue ?
