"AMD64 Fedora Rawhide Clang 3.x" buildbot worker is currently broken:
https://buildbot.python.org/all/#/builders/169/builds/168
clang cannot build (statically linked) binary using UBSan:
I reproduced the issue on the worker. The issue comes from a version conflict between clang and compiler-rt packages:
compiler-rt-9.0.0-1.fc32.x86_64 uses /usr/lib64/clang/9.0.0/...
vs
clang-9.0.1-2.fc32.x86_64 uses /usr/lib64/clang/9.0.1/...
Charalampos created https://src.fedoraproject.org/rpms/compiler-rt/pull-request/10 to propose to update compiler-rt.

Charalampos downgraded clang to 10.0.0 to workaround the issue. The buildbot worker compiles the code succesfully again:
https://buildbot.python.org/all/#/builders/169
I close the issue. The issue is now tracked in Fedora Rawhide anyway:
