Actually the bug that you experience most likely comes from openblas,
not from octave. I'm therefore reassigning this bug to the right
package.

Note that openblas uses different codepaths depending on your CPU, so I
need more information to move forward.

In order to get more information about your setup, could you please
install the "julia" package (it will pull openblas again), run "julia"
at the shell prompt, then type "versioninfo()" at the julia prompt.

For information, here is the output on my machine:

julia> versioninfo()
Julia Version 0.3.10
Platform Info:
  System: Linux (x86_64-linux-gnu)
  CPU: Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz
  WORD_SIZE: 64
  BLAS: libopenblas (NO_LAPACKE DYNAMIC_ARCH NO_AFFINITY Haswell)
  LAPACK: libopenblas
  LIBM: libopenlibm
  LLVM: libLLVM-3.5

Thanks,
