Thanks for the suggestions -
I had already scoured the 64-bit transition guide, and didn't think I
needed to use NSInteger and CGFloat since integers and floats appear
to be the same size for both 32 and 64 bit builds.
Just to be sure though, I tried replacing any int and float
declarations touching this code with NSInteger and CGFloat, but I
still got the problem.
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.
