"Segmentation Fault - core dumped" in R 0.62.3
I am occasional getting "Segmentation Fault - core dumped" in R 0.62.3 (I think
more often then I did in 0.62.2). I have not been able to do this in any
reliably reproducible way yet, but thought I would mention the problem in case
some else can isolate it.
