I've tried building scipy 1.1.0 from github on a Fedora installation. The build already uses -funroll-loops. But I couldn't reproduce the problem with the resulting binary.
gcc version 8.0.1 20180324 Aurelien already tracked it down to a miscompilation of scipy/optimize/minpack/qrsolv.f This source file appears to contain just a single function (qrsolv) which is not too big. I think I can work with that after being able to reproduce the problem. As Jakub mentioned the exact compiler cmdline would be good. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1811798 Title: gcc 8 miscompiles scipy/optimize/minpack/qrsolv.f To manage notifications about this bug go to: https://bugs.launchpad.net/gcc/+bug/1811798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
