--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Orion Poplawski from comment #10) > With gcc-7.0.1-0.4.fc26, we no longer get ICEs, but hdf5, openblas fail > their tests on ppc64le, and python2/numpy appears to segfault in tests. So > something does not appear to be right. Please file PRs with details in the Fedora bugzilla. I see e.g. hdf5 built yesterday, so it is unclear what issues you are seeing.
