Yes, that's what I've found. I can also confirm that compiling with 1 thread works around it. It's only a problem w/ gmake -jN where N is > 1 (I run w/ 8 or 12 or so typically).

Intresting, adding Jens, hopefully he has some good idea.

Maybe you could re-add 'macroexpand' and 'rename-buffer' to
'native-comp-never-optimize-functions' and discover which one of the two is triggering the bug?

I can't try it just now, but my trace includes: `File already exists: /private/var/tmp/emacs-plusA30-20231227-10652-1cz0rs/.brew_home/.emacs.d/eln-cache/30.0.50-69afc345/subr--trampoline-6d6163726f657870616e64_macroexpand_0.eln` so I'm guessing it's macroexpand.
