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

That's weird, because I can repro it (cross-compiling for |

@SNCPlay42 on the latest nightly? |

@compiler-errors yep: Also the version of winit from the report ( |

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

Whoops, I seemed to have caused it 😆 I'll look into it! |

…ments-twice, r=cjgillot Don't record adjustments twice in `note_source_of_type_mismatch_constraint` We call `lookup_method` a few times in `note_source_of_type_mismatch_constraint`, but that function has side-effects to the typeck results. Replace it with a less side-effect-y variant of the function for use in diagnostics. Specifically the ICE in rust-lang#112532 happens because we're recording deref adjustments twice for a call receiver, which causes `ExprUseVisitor` to be angry. Fixes rust-lang#112532
