log of buildworld failing on ASAN heap overflow detection in llvm-ar

We at HardenedBSD have a special feature branch that applies ASAN to every application in base[1]. As such, ASAN gets applied to llvm-ar.

It appears ASAN reports a heap overflow in llvm-ar (we've also switched to llvm-ar as the system's ar/ranlib).

Build log is attached.
