Jin Shang commented on ARROW-17728:
-----------------------------------
I think it's because pacman updates its LLVM version to 15.0.0 a few days ago
([https://github.com/msys2/MINGW-packages/commit/babbba3822e209de5dc3faec5a38f9f3dda8a266)]
and arrow doesn't accept LLVM 15 yet. I'll submit a PR to fix this.
