I could still reproduce this with upstream Clang instead of Apple Clang.

I can't reproduce the problem with the commands listed in the original issue. Could you share a repro case with me?

I used Clang and LLD built from commit 0e4378c.

I had a stale build. Yeah, it was fixed. Apologies for the false alarm.
