Does anyone have a working configuration for running CI on Github 
on MacOS? I just tried macos-15 and macos-15-intel and both of 
them have bizarre failures.

macos-15:

Use dmd master instead.

[Dlang.nix](https://github.com/PetarKirov/dlang.nix) has one. Or 
had, at least... Petar had some strange failures for [the exact 
same build that did compile on 
olderr](https://github.com/PetarKirov/dlang.nix/pull/173#issu
comment-3490813046) Macs.

Check [this issue](https://github.com/dlang/dmd/issues/21126). I 
don't understand how it could be causing dlang.nix failures since 
we're supposed to be using a bootstrap compiler that isn't 
affected (ldc 1.25.0) but who knows. I don't think it's behind 
your problem as that particular issue causes crashes, not linking 
failures but again, who knows.
