The following typed into R --vanilla induces a crash:
-- cut here --
gctorture()
u <- intToUtf8(c(rep(1e3,1e2),32,c(rep(1e3,1e2))))
v <- rep(u,1e2)
v <- sub(" ","",v)
v %in% ""
-- cut here --

sessionInfo() says:

-- cut here --
R version 2.10.0 (2009-10-26)

locale:
[1] LC_COLLATE=German_Germany.1252  LC_CTYPE=German_Germany.1252   
[3] LC_MONETARY=German_Germany.1252 LC_NUMERIC=C

attached base packages:

I apologise for not testing this with R-2.10.1 but as far as I can see there are
only source releases available so far, which I am not able to compile.

Best wishes and thanks,

George Russell
