This is failing due to a GCC 15 internal compiler error.

I opened https://src.fedoraproject.org/rpms/embree/pull-request/5 with a proposed workaround for the FTBFS, and opened 2342604 to track the compiler bug separate from the FTBFS.

The compiler bug 2342604 was fixed, so the workaround is no longer needed.

However, we shouldn’t rebuild this right now against OpenImageIO 3, since it would probably have to be rebuilt again later: https://bugzilla.redhat.com/show_bug.cgi?id=2339934#c23

The OpenImageIO rollback landed in https://bodhi.fedoraproject.org/updates/FEDORA-2025-897b07ab39.

Now we just need to wait for the GCC update https://bodhi.fedoraproject.org/updates/FEDORA-2025-0c4b748361, which is held up in CI gating, before we can actually do a rebuild.

Successfully rebuilt in https://bodhi.fedoraproject.org/updates/FEDORA-2025-7fe96ea92f.
