readLines without skipNul=TRUE causes crash
hi, i realized that the segfault happens on the text file in a new R
session. so, creating the segfault-generating text file requires a
contributed package, but prompting the actual segfault does not -- pretty
sure that means this is a base R bug? submitted here:
https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17311 hopefully i am
not doing something remarkably stupid. the text file

readLines without skipNul=TRUE causes crash
hi, thanks Dr. Murdoch
i'd appreciate if anyone on r-help could help me narrow this down? i
believe the segfault occurs because there's a single line with 4GB and also
embedded nuls, but i am not sure how to artificially construct that?
the lodown package can be removed from my example.. it is just for file
download cacheing, so `lodown::cachaca` can be replaced with
`download.file`
