It's a bug. ATLAS is built with g77 as Fortran compiler, while Octave
(2.9.9) was built with gfortran. This results in bugs when working with
complex numbers.

There's not much we as maintainers can currently do. We are waiting for
Octave 2.9.12 to migrate to testing (it's waiting for an ARM build on a
machine with enough ram[1], but mails to arm@buildd.debian.org yield no
result).
