compiler-errors commented 1 year ago

Do you mind checking if this still ICEs on the most recent nightly?

jembishop commented 1 year ago

I just did that now, and it looks like the issue is fixed on the latest nightly. (sorry should have tried that in first place!)

SNCPlay42 commented 1 year ago

That's weird, because I can repro it (cross-compiling for aarch64-apple-darwin from linux if it matters).

compiler-errors commented 1 year ago

@SNCPlay42 on the latest nightly?

SNCPlay42 commented 1 year ago

@compiler-errors yep:

note: rustc 1.72.0-nightly (7820972f8 2023-06-10) running on x86_64-unknown-linux-gnu

Also the version of winit from the report (winit-0.22.2) is not the latest and appears to fail to compile (non-ice) on stable. I'm working on bisecting and reducing now

SNCPlay42 commented 1 year ago

Wait, this actually ICEs on stable too and I didn't notice because rustc emitted a bunch of errors after the ICE (?!)

SNCPlay42 commented 1 year ago

I've reduced it down to this (which is no longer macOS or aarch64 dependent):

pub trait NSWindow: Sized {
    unsafe fn frame(self) -> () { unimplemented!() }
    unsafe fn setFrame_display_(self, windowFrame: (), display: ()) {}
}
impl NSWindow for () {}

pub struct NSRect {}

use std::ops::Deref;
struct MainThreadSafe<T = ()>(T);
impl<T> Deref for MainThreadSafe<T> {
    type Target = T;

    fn deref(&self) -> &T { unimplemented!() }
}

pub unsafe fn set_maximized_async(ns_window: ()) {
    let ns_window = MainThreadSafe(ns_window);
    move || {
        unimplemented!() = {
            NSWindow::frame(*ns_window);
            unimplemented!()
        };
        ns_window.setFrame_display_(unimplemented!(), 0);
    };
}

(The assignment to unimplemented!() was of course something more reasonable in the original code, but now I can't seem to replace it without making the ICE go away)

This failed to compile without ICE on 1.69:

Whoops, I seemed to have caused it 😆

I'll look into it!
