Despite a few minutes of Googling I am unsure of whether this has been reported, but if it hasn't the following reliably crashes R "seg fault", on, if it matters, my Linux box
sample=data.table(a=1:50,b='N') sample[50,b:=c(1,2,3)] I don't know the guts of data.table to know whether it'd be easy to error check without sacrificing performance. At the very least maybe some helpful output?
