I ran the example from the guy for whom qhull coredumps on my
octave 2.1.34 with octave-forge from Nov 02 on Lintel:

      ......
    >       7.378 125.8 78.648553
    >       7.378 129.5 78.241684 ]  ;
    octave:3> 
    octave:3>  X = T(:,1) ;
    octave:4>  Y = T(:,2) ;
    octave:5>  A = X + Y ; ## stupid
    octave:6>  delaunay(A,X) ; # works
    octave:7>  delaunay(X,Y) ; # doesn't work
    octave:8> plot(x,y)
    panic: Segmentation fault -- stopping myself...
    attempting to save variables to `octave-core'...
    save to `octave-core' complete
    Segmentation fault

so, indeed, there's something fishy going on. Even though I don't get
an immediate coredump after the second call to delaunay(), I get a
reliable crash when I try to do something else---looks like some
serious internal corruption. Thanks for finding a good, nasty test case!
