However, 16.04 xenial is already on binutils-2.26 and would not be restricted by this build requirement change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663280 Title: Serious performance degradation of math functions To manage notifications about this bug go to: https://bugs.launchpad.net/glibc/+bug/1663280/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
