I've tried to reproduce the problem with Netlib BLAS, OpenBLAS and BLIS, but without success (I did not try with MKL since I don't want such a large binary blob on my system). Basically you're suggesting that Octave's basic matrix multiplication functionality is utterly broken, without anybody else noticing. This is highly unlikely. Did you try to reproduce the problem on a pristine sid chroot, or another system?
