thanks, simon. it's replicable even on R version 3.0.1 Patched (2013-07-13 r63293) -- "Good Sport"
(I presume that it is loading its own updated dynamic libraries when I installed it in a temporary directory and am invoking it as "temp/R-patched/bin/R", and not the system-wide unpatched version.) the program that causes it is small enough to be displayable if (interactive()) options(error=recover) year <- 1982 for (yr in (year-6):year) { ifname <- paste0("dbetas/dbetas-",yr, ".Rdata") load(ifname) print(head(dbetas,2)) ## if you remove this, then the core dump goes away dm <- if (!exists("dm")) dbetas else rbind(dm, dbetas) cat("[Loaded ", yr,"]\n") } cat("\n[", now(), "Loaded All Data]\n") Reproducing the error, # r-devel/R-patched/bin/R --vanilla R version 3.0.1 Patched (2013-07-13 r63293) -- "Good Sport" Copyright (C) 2013 The R Foundation for Statistical Computing Platform: x86_64-unknown-linux-gnu (64-bit) R is free software and comes with ABSOLUTELY NO WARRANTY.
