Alas, bad news. I have rebuilt everything with lapack-3.2.1 and I'm still
getting segfault with roots(rand(1, 13)), but not with roots(rand(1, 12)):

"
octave:1> roots(rand(1, 12))
ans =

  -437.06494 +   0.00000i
    -0.92565 +   0.31860i
    -0.92565 -   0.31860i
    -0.62606 +   0.75980i
    -0.62606 -   0.75980i
     0.13259 +   1.27016i
     0.13259 -   1.27016i
     0.79830 +   0.47988i
     0.79830 -   0.47988i
     0.43001 +   0.78468i
     0.43001 -   0.78468i

octave:2> roots(rand(1, 13))
panic: Segmentation fault -- stopping myself...

- that's still with octave-3.0.5.
