Probable upstream bug: https://github.com/rizsotto/Bear/issues/309

Comment 1 Ben Beasley 2021-05-11 21:22:00 UTC

I ran into this while preparing to submit a PR to rebuild bear in a side-tag for a grpc update in Rawhide.

In the absence of an actual fix, the obvious solutions would seem to be:

  a. Disable the unit tests on s390x, and hope the resulting package is not too broken. Or:
  b. Add an ExcludeArch: s390x; link this bug, and block F-ExcludeArch-s390x from this bug.

What do you think? I can incorporate your preferred fix or workaround into the PR to rebuild for the grpc update.

(Link for the ExcludeArch option: https://docs.fedoraproject.org/en-US/packaging-guidelines/#_architecture_build_failures)

Comment 3 Ben Beasley 2021-05-13 12:11:26 UTC

I’ve worked on this some with upstream at https://github.com/rizsotto/Bear/issues/309. I was able to offer a backtrace, and I observed that the problem goes away when LTO is disabled, which is a good workaround for now.

I will provide a PR.
