As usual I'm sure it will turn out to be some silly small thing (and
not a mysterious alignment issue with CBLAS). The strange thing is
that the problem only arises when the matrices involved exceed a
certain size.
After further testing with simplified test cases, I think it actually
I've been tesing a 64 bit build of an application that uses the BLAS
function cblas_sgemm to multiply two matrices. The code works fine in
32 bit builds (building with Xcode 3.0 on Leopard 10.5.3)
There is a strange problem that I think I have isolated to the output
of the above
