On a related note, it also fails on ppc64be with a different error though:

Thanks for the report. Will add it to ExcludeArch for now - been meaning to wait until there's a version that's buildable on F23 / rawhide (LLVM JIT changes) but upstream said it might take until the end of summer before one is available. Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
