Thanks for helping. Do you use openblas or Apple's implementation via 
vecLibFort, [1]? My problems occur only in the latter case, i.e., it works 
perfectly with openblas.

I have currently no clue what's going on. The problem might be restricted to 
homebrew. Nonetheless, on my mac (10.11) octave 4.0.0 works while octave 4.0.1 
segfaults. Since all other settings are identical some change in Octave should 
be causing the trouble.
