I can't find any mention that the BLAS routines use SSE (or any other
SIMD extensions). In fact the header file suggests they don't.
The 64-bit ABI requires 8-byte alignment, but I cannot find any
mention that 8-byte alignment is required for 32-bit code. In fact
the docs explicitly state this is not the case.
So I currently have no idea why the BLAS code would fail without
8-byte alignment.
