Hi, Strange... Let me bring this upstream to see whether this is flexiblas' or openblas' fault. In the meanwhile, exporting FLEXIBLAS=netlib before the tests makes use of the reference implementation, so everything should be slower but safer. And if this starts happening in the wild, we can change to openblas-serial with a quick update of FlexiBLAS.
