--- Comment #3 from Richard Jones <rjones at redhat.com> ---
This turned out to be because of the Fedora compiler-rt
package.  I had compiler-rt-12.0.0-1.fc35.x86_64 installed,
which did not exactly match the clang version.  Upgrading to
compiler-rt-12.0.0-2.fc35.x86_64 fixed it.

I guess Fedora needs to use an exact NVR dependency.
