Hi
Thanks for narrowing down the problem.
I have committed some more defensive code and a change that fixes the
problem (for me ...
R version 2.13.0 Under development (unstable) (2010-09-28 r53056)

That is more serious. I have heard of a couple of others like this and
I think the common thread may be 64-bit MacOS X.
I need to get access to such a beast to take a look.
Or maybe just 64 bit. I have (running Debian unstable)
sessionInfo()
R version 2.12.0 Under development (unstable) (2010-09-02 r52864)
Platform: x86_64-unknown-linux-gnu (64-bit)
and I get reproducible crashes (same 'memory not mapped' segfault) with
x11(type="Xlib")
example(rasterImage) #or
library(lattice)
example(panel.levelplot.raster)
[I noticed this a while back, but neglected to report.]

I can confirm the problem exists in 2.11.1 as well on 64 bit Ubuntu:
R version 2.11.1 (2010-05-31)
x11(type="Xlib")
example(rasterImage)
rstrIm> require(grDevices)
rstrIm> ## set up the plot region:
rstrIm> op<- par(bg = "thistle")
rstrIm> plot(c(100, 250), c(300, 450), type = "n", xlab="", ylab="")
Hit<Return> to see next plot:
rstrIm> image<- as.raster(matrix(0:1, ncol=5, nrow=3))
rstrIm> rasterImage(image, 100, 300, 150, 350, interpolate=FALSE)
*** caught segfault ***
address 0x28, cause 'memory not mapped'
Traceback:
1: rasterImage(image, 100, 300, 150, 350, interpolate = FALSE)
2: eval.with.vis(expr, envir, enclos)
3: eval.with.vis(ei, envir)
4: source(tf, local, echo = echo, prompt.echo = paste(prompt.prefix,
getOption("prompt"), sep = ""), continue.echo = paste(prompt.prefix,
getOption("continue"), sep = ""), verbose = verbose, max.deparse.length =
Inf, encoding = encoding, skip.echo = skips, keep.source = TRUE)
5: example(rasterImage)
The lattice example in Deepyan's email
library(lattice)
example(panel.levelplot.raster)
works for me in 2.11.1
