Ouch, another obscure bug...
I just had a bus error crash, with a core dump, a small one this time.
Usual <URL:http://www.astro.uio.no/~kjetikj/tmp/core>.
I had done a few simulations, and done a chisq.test() on them.
These simulations also write about 190MB's to file, but
I have no idea whether that is relevant, and those data are not
used. The calls I do look like this:
> ch1 <- chisq.test(t(apply(cbind(rep(5000000, 4)), 1, lineprofile, 1, 100,
"point")))
> ch1

	 Pearson's Chi-square test 

data:  t(apply(cbind(rep(5e+06, 4)), 1, lineprofile, 1, 100, "point")) 
X-squared = 463.8359, df = 300, p-value = 3.726e-09 

> ch1$observed

....so it doesn't crash when I print the whole object, but when I 
a vector of the object, it crashes... And, restarting R, it doesn't
happen.

I heard the sysadm who did the installation had some problems,
I don't know what it was about, but if I understood him correctly,
it only happened when he tuned for EV6, so it shouldn't be a problem now, 
I guess....
