I went back and compiled older versions of R to see if this error
exists.  On R 3.0.3, I get:

install.packages('ggplot2', dep=TRUE, repo='http://cran.stat.ucla.edu')
debug: z <- res0 <- tryCatch(read.dcf(file = tmpf), error = identity)
Error: segfault from C stack overflow

On R 2.15.3, I do not see the error.
