So is this a bug in ATLAS 3.8.x or a change in the interface to some
LAPACK subroutine, or what?

It might help if someone who can reproduce the problem would run
Octave under GDB and find precisely where the crash occurs, and maybe
diagnose why the crash is happening.  Are we calling an LAPACK
function incorrectly?  Not passing sufficient workspace?  What?
