Segmentation fault
However, using R Version 1.7.0 (2003-04-16) installed using Fink on Mac OS X, the .sav file reads without a problem.
The .sav file has in its header the following reference:
SPSS DATA FILE SPSS for Unix Release 6.1 (HP9000 700 )
Although for the moment I'm reading in a Mac OS X R save'd version of the SPSS data file, I would like to read in the original .sav file. Does anyone know what the problem might be? The .sav file can be downloaded from:
http://viropage.psy.cmu.edu/~rijn/dataDef.sav.bz2 (approx 100 kb)

A couple of months ago, probably using an older version of R, R used to run the following code just fine:
library("foreign") data.exp1 <- as.data.frame(read.spss("dataDef.sav"))
Issuing the same commands now (after starting R using --vanilla), gives me the following behavior:

Segmentation fault
The first two assignments return instantaneously, after the second x contains all original SPSS variable/column names but no data, after the last read.spss - it takes a while before R returns with the Segmentation fault. During that time, the harddisk seems to be working quite hard.
Does anyone know what the problem might be?
