zsh: abort (core dumped) zig build

```

No idea where to begin here. I’m not even sure if this is a zls problem or a zig problem (my best guess is zig itself).

Yes that’s a crash in the compiler. Can you clean both the local `zig-cache` and the global one? Which version of Zig are you using?

It will have to wait until I’m home in a couple of hours. It’s version 0.11.0.

Cleaning the global cache fixed it. Thanks kristoff.

Now I need to figure out why it immediately exits, but that’s another story…
