Looks like this issue existed in LLVM 22.1.0 (the culprit https://github.com/llvm/llvm-project/commit/55aff64d2c6ef50d2ed725d7dd1fb34080486237 was introduced in November of last year).

This is another assertion that I have found when attempting to build Rust on PPC64 AIX, as LLVM is pinned to a specific 22.x release version.
