Can you reproduce this on the compiler-builtins repo? What command did you run, and how does config.toml look?

As we've discussed elsewhere, I've already diagnosed this for Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=1797127

This is an LLVM bug, and LLVM 9 (as bundled with rustc) is already fixed. This will need to be patched in your system LLVM.
