I was not able to reproduce the problem.

The option -f66 may be the culprit. It changes the semantics of DO
loop so that they are executed at least once, even if the upper bound
is less than the lower bound. Can you try without?

Are you using this option both within Cactus and when building
LAPACK/BLAS stand-alone?
