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.
