Subject: [Rd] read.spss, R 1.3.0, win2k

I've found the problem.  The read.spss code was free-ing not Free-ing
memory allocated by Calloc.  On most platforms that would work, but not on
Windows where Calloc/Free and calloc/free use separate memory managers.

This explains the randomness of the problems.

I'm solving this (and a few other things) in 0.4-6.
I will put up a pre-compiled version, so update.packages() should fetch it
tomorrow.

This is already solved in 0.4-5.
