Bevy version

0.9.0

Relevant system information

Macbook Pro 2018 2.9 GHz 6-Core Intel Core i9 Intel UHD Graphics 630 1536 MB AMD Radeon Pro 560X

MacOS Ventura 13.0 cargo 1.65.0 (4bc8f24d3 2022-10-20)

What you did

use bevy::prelude::*;

fn main(){
  App::new()
    .add_plugins(DefaultPlugins)
    //.add_system(hello_world) // Also broken
    .run();
}

// fn hello_world() {
//   println!("hello world!");
// }

What went wrong

• what were you expecting?

Successful basic hello world, or to just output nothing

• what actually happened?

It appears to be some sort of metal incompatibility with wgpu

note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

Additional information

• It runs on Bevy 0.8.1, so the issue is very likely a change between those versions.
• This issue is similar but likely unrelated

[superdump]

Interesting. @cwfitzgerald - the backtrace of this segfault is in wgpu. Any ideas?

[rparrett]

Hey 10Nates -- any chance you could give this a try with Bevy 0.11?

I'm unable to reproduce even with Bevy 0.9.0, but only have access to an M1 mac.

[10Nates]

Just checked, appears to be working now. Must have been resolved somewhere at some point.
