R Crashes when using "large" matrices (Ubuntu 11.04)

Hello,

This simple SVD calculation (commands are copied 
immediately below) crashes on my Ubuntu machine (R 2.13.0). However it 
works fine on my Windows 7 machine, so I suspect there's a problem with 
(my?) Ubuntu and / or R. Can anybody else reproduce it (with Ubuntu 
11.04)? Thanks in advance.

p <- 500
n <- 300
set.seed(1234)
x <- matrix(rnorm(n*p), n, p)
sih <- var(x)
b <- svd(sih)

produces:

?*** caught illegal operation ***
address 0x42b8c9, cause 'illegal operand'

Traceback:
?1: .Call("La_svd", jobu, jobv, x, double(min(n, p)), u, v, "dgsedd",???? PACKAGE = "base")
?2: La.svd(x, nu, nv)
?3: svd(sih)

I'm using Ubuntu 11.04 and
