[BGR360]

Shoot, I'm unable to attempt a repro on my machine since ovr_overlay_sys won't build on Mac :/

[BGR360]

Is there any chance you could work to put together a more minimal repro with fewer dependencies? I know that's a lot to ask but it would be a massive help.

Also, can you clarify: is it just adding eyre to your Cargo.toml that breaks things? Or are you doing something with it? The backtrace looks vaguely like it's coming from trying to expand a proc_macro. Are you using some macro from the eyre crate?

I also see a line in the backtrace that references the compiler's incremental compilation serialization/deserialization. Can you try doing a cargo clean and see if that resolves things?

[compiler-errors]

I think this is #101640

[TheButlah]

I can attempt to make a more minimal example. Will take some work, but will update when its done. Probably won't happen in the next day or two though.

[compiler-errors]

I wouldn't bother -- can you try updating your nightly compiler and seeing if this persists? see my previous comment, I think this is #101640 and therefore already fixed.

[TheButlah]

I no longer get an ICE, instead I get a bunch of errors about missing types, presumably because once_cell was not passed the no_std flag
