Hi,
I'm experiencing R segmentation faults on multiple versions of R
when writing out a particular data.frame:
## dd is a 44 by 3 data.frame
load(url("http://stat.bell-labs.com/RS-DBI/download/dd.rda";))
write.table(dd, file = "dd.csv", sep = ",", row.names = FALSE)
this occurs on
> sessionInfo()
R version 2.2.0, 2005-10-06, i686-pc-linux-gnu
attached base packages:
[1] "methods" "stats" "graphics" "grDevices" "utils" "datasets"
[7] "base"
> sessionInfo()
R version 2.2.1, 2005-12-20, i686-pc-linux-gnu

*** caught segfault ***
address 0x18, cause 'memory not mapped'
Traceback:
1: write.table(dd, file = "dd.csv", sep = ",", row.names = TRUE)
Possible actions:
1: abort (with core dump)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: 3
