I have built openblas 0.3.15 locally, and confirmed that it works fine with Core i7 870 (Lynnfield). I will test it if you provide the test version of 0.3.15. P.S. The same issue happnes also with Xeon X5680 and v0.3.14. -- Takashi Yano -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
