Look at the post of Martin Krischik, 20.10.06 18:30 CET... it > shows the most serious testing so far, with the exact sources used for > testing. Sorry for this. I'll go back to my silent lazy listening after this message :-) S. Tardieu had also suggested this layout issue in one message and I didn't follow the links given by M. Krischik. Anyway, independently of compiler bugs or limitations, differences in matrix layout leads to different (non strictly equivalent) programs! Which was precisely a question asked by J. Creem in his first sentence ! Regards Damien
