I'm not sure if the automation that reports failures from buildbots back to the PR got broken, but I can report that this seems to fail for the RISC-V RVA23 config (vector enabled) https://lab.llvm.org/buildbot/#/builders/132/builds/597 but not the RVA20 build done at the same time.

The error on the RVA23 builder is:

```
