To learn more about what is going on here, I built both PSPP
0.4.0 and the latest version from CVS on pergolesi.debian.org in
a 64-bit chroot. On "make check" on 0.4.0, about half of the
tests failed. With the latest CVS snapshot, however, all tests
passed, and the example program worked fine.
I don't think that PSPP 0.4.0 is going to perform satisfactorily
on x86-64. The upcoming release, and the current CVS for that
matter, should be much better.
(I am currently fielding a few problems with support for
big-endian systems though. But those should be pretty easy to
fix.)
