Based on this and Alex' message it seems the offender is the f2c generated lapack_lite library.
So do we do with lapack_lite? Should we patch it?

Even if lapack_lite always performed the isfinite check and threw a python error if False, it would be much better than either hanging or segfaulting and people who care about the isfinite cost probably would be linking to a fast lapack anyway. -Dave
