You're R < 2.14.0, right? I'm really struggling in R < 2.14.0 to make over-allocation work because R only started to initialize truelength to 0 in R 2.14.0+. Before that it's unitialized (random). Trouble is my attempts in R < 2.14.0 to work around that work fine for me in linux 32bit when I test in R 2.13.2, and I even test in 2.12.0 too. I test on 64bit too but just 2.14.0. CRAN is also showing errors on 2.13.2 (old-rel) for both mac and windows.
So, this is a pre-2.14.0 (only) problem that I'll continue to try and fix. Are you 64bit pre-2.14.0? Which OS? If you are 64bit linux then it adds weight to me installing pre-2.14.0 on my 64bit instance in an effort to reproduce. > This will be a crappy help request because I can't seem to reproduce > it, but the past few days I've been getting a lot of segfaults.
