You are presumably hitting the switch from dayligh-saving to regular time in
that year.
I was just mucking about with that, but R (1.9.0 as of Jan 8, 2004, on
Debian unstable) still crashes reliably even when I explicitly set the TZ
variable (and it also crashed for TZ=GMT):

TZ
""
> Sys.putenv("TZ"="CDT6CST")
> Sys.getenv("TZ")
TZ
"CDT6CST"

tz="GMT", usetz=TRUE)

Segmentation fault
Not nice. I wrote some code to transfer time stamps from one time zone to
another, but that sits at work right now and I can't get to it...
