I can confirm the problem exists in 2.11.1 as well on 64 bit Ubuntu:

R version 2.11.1 (2010-05-31)

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
