regression problems

I'm having a hard time getting the regression command to do anything
sensible.  Below is  a simple example from a trusty spss for dummies book
I have.

The first regression command quits with the error "memory exhausted"
(note to self: should catch this and call custom handler).
The second two both crash with different errors.  One with an
assertion failure the other a plain segmentation fault.
