I have an affinity to "--ffloat-store" rather than to a play with optimization flags because it seems to me that "--ffloat-store" addresses the problem directly, while the "fix" with a lower optimization seems like a fortuitous side effect. Is there a firm rule on which optimizations are allowed at which -Ox level? I always assumed that -O2 (and below) is a "safe" level which should not break the conformant code. So, the real solution would be to fix the blas/lapack code. > > -Quentin > Sincerely, Dmitri. -- ------------------------------------------------------------- Octave is freely available under the terms of the GNU GPL.
