I've got the reorganized version from cvs and still don't get a segfault using the distro BLAS and gcc 3.4.2.

I did a fresh checkout, b/c I recalled hearing about a discussion on a

ATLAS provides a tuned BLAS, optimized for your specific architecture.  The 
functionality is the same as that in Fedora's generic BLAS, but the 
performance is higher.
