Bevy App with DefaultPlugins Segfaults on M1 Mac

[hedonhermdev]

Bevy version

bevy = "0.12.0"

Relevant system information

bash-5.2$ rustc --version
rustc 1.75.0-nightly (edf0b1db0 2023-11-10)

AdapterInfo { name: "Apple M1 Pro", vendor: 0, device: 0, device_type: IntegratedGpu, driver: "", driver_info: "", backend: Metal }

What you did

Tried running code from the tutiorial. I think this is the minimum version of the code that fails for me. I am not very familiar with the ecosystem but happy to help isolate the issue further.

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .run()
}

What went wrong

Bevy app segfaults after printing a single line of tracing log.

2023-11-12T18:31:48.332656Z  INFO bevy_render::renderer: AdapterInfo { name: "Apple M1 Pro", vendor: 0, device: 0, device_type: IntegratedGpu, driver: "", driver_info: "", backend: Metal }
Segmentation fault: 11

Running with lldb seems to be helpful in isolating the issue to wgpu_core

If it helps, I'm also running this in a nix environment.

`flake.nix` for reference

      {
        devShell = pkgs.mkShell {
          nativeBuildInputs = with pkgs; [
            rustToolchain
            rustPlatform.bindgenHook
            darwin.libobjc
          ];

          buildInputs = pkgs.lib.optionals pkgs.stdenv.isDarwin
            (with pkgs.darwin.apple_sdk.frameworks; [
              AudioToolbox
              AudioUnit
              CoreAudio
              OpenAL
              AppKit
              Metal
              MetalKit
            ]);
        };
      }

[mockersf]

Works for me without nix. Can you check?

[hedonhermdev]

Is the AdapterInfo output I see as expected? Am I supposed to see something in the driver output?

I am unable to compile the app when I try without Nix. I get an AudioInit/AudioInit.h missing error.

[hedonhermdev]

Hmm, tried on a fresh user profile without nix, seems to work. Will try to isolate the issue on the nix end.

[sergeypdev]

I have the same problem without nix.

The problem only appears when I have

[profile.dev.package."*"]
opt-level = 3

opt-level = 0, 1 and 2 work fine.

[gak]

Also got a segfault on startup, M2 Max.

@sergeypdev's suggestion worked, but also switching from nightly to stable worked (while having opt-level = 3).

Also, not using nix, and on Sonoma 14.1. sccache.

[Patryk27]

Same here (I'm also using Nix, but not in this particular project - there's just Nix installed on my system, but no flake.nix etc. in the project's directory).

In my case it reliably crashes when dropping a vector, though:

edit: works in debug mode, though!

[Patryk27]

Seems to have been reported at rust-lang/rust#117902 - the recent working toolchain is nightly-2023-10-18.

Edit: it looks like disabling cross-crate inlining "solves" the issue, i.e.:

RUSTFLAGS='-Zcross-crate-inline-threshold=0' cargo run --release

[lee-orr]

Running into this with dexterous_developer as well - for now lowering the optimizations on bevy, but looking forward to a resolution.

[gak]

Just updated nightly: rustc 1.76.0-nightly (a96d57bdb 2023-12-15) (from rustc 1.76.0-nightly (a57770440 2023-11-16))

.. and the segfault went away when using opt-level = 3

Looks like the related issue is fixed: rust-lang/rust#117902 (comment)
