STATUS_ACCESS_VIOLATION when running rend3 on Windows MSVC linked with LLD and thin LTO

[Elabajaba]

I'm getting a crash when running the rend3 examples in --release mode with lto=thin and using LLD. (edit: Happens in both dev builds and release builds when using thinLTO)

Rend3 repo: https://github.com/BVE-Reborn/rend3
Tested commit: 4d107951a3ba62a58a7be1849eb670d05f269e20

I expected to see this happen: It doesn't crash instantly when attempting to run it.

Instead, this happened: It crashes instantly when attempting to run the examples.

After checking out the same commit and ensuring I was running thin LTO with lld-link (CARGO_TARGET_X86_64_PX_WINDOWS_MSVC_LINKER="lld-link" cargo +nightly-x86_64-pc-windows-msvc run --bin cube --config 'lto="thin"') I can't seem to reproduce this on latest nightly -- was this already fixed perhaps?

I've run all of the examples with the exception of the imgui one (it panics on imgui-winit-support not being upgraded and this is taking enough time already). Are there any other environment-specific things that could've caused this?

[Elabajaba]

I'm still able to reproduce it both on the earlier commit listed in my original post and on the latest rend3 commit (d7806f584468c4ed974a2ff5e1eea547d26478db) on rustc stable 1.74.0 (79e9716 2023-11-13), stable 1.74.1, and 1.76.0-nightly (3340d49 2023-12-12) by running the cube example with lto="thin" set in Cargo.toml (both for debug builds and release builds).

Based on how long it takes to build the final cube.exe, cargo run --bin cube --config 'lto="thin"' doesn't appear to be working on stable or nightly for me. --timings shows 0.87s to build the cube binary with --config 'lto="thin"', vs 15.75s if I add it to the Cargo.toml

[profile.dev]
lto = "thin"

That seemed long so I checked by setting lto = "fat" in Cargo.toml and it took 52.24s and the binary worked.

I removed everything in my global ~\.cargo\config.toml except

[target.x86_64-pc-windows-msvc]
linker = "rust-lld.exe"

I also tested linker = "lld-link.exe" using the version of LLD included with the scoop installer llvm package (LLD 17.0.6), and it has the same issue.

[RivenSkaye]

Would you happen to have an MinGW env lying around? I used the lld-link.exe from there for my testing. I'll rerun things tomorrow with rust-lld to see if I can reproduce. If not, I wonder if there's some optimization step going wrong considering the system I ran this with is rather outdated

[ChrisDenton]

This still reproduces. Steps I took...

Firstly download the repo in the OP and switch to the indicated commit:

git clone https://github.com/BVE-Reborn/rend3.git
cd rend3
git switch --detach 4d107951a3ba62a58a7be1849eb670d05f269e20

Then I edited .cargo/config.toml to add the following (x86_64-pc-windows-msvc is both the host and target):

[target.x86_64-pc-windows-msvc]
linker = "rust-lld"

Finally run an example to see the crash:

cd examples/animation
cargo run --release

This fails with STATUS_ACCESS_VIOLATION.

I then edited the Cargo.toml in the root of the repo so to turn off optimizations but still keep lto=thin. This allowed me to capture a more detailed backtrace.

This points to using atomic_compare_exchange from once_cell but I think things start going wrong earlier in winit. Specifically: https://github.com/rust-windowing/winit/blob/2ebbfab6a47f93f76841553dcb3cc53683e4955c/src/platform_impl/windows/event_loop.rs#L700

lpszClassName: THREAD_EVENT_TARGET_WINDOW_CLASS.as_ptr(),

THREAD_EVENT_TARGET_WINDOW_CLASS is defined as:

static THREAD_EVENT_TARGET_WINDOW_CLASS: Lazy<Vec<u16>> =
    Lazy::new(|| util::encode_wide("Winit Thread Event Target"));

So my assumption is the static isn't getting linked correctly for some reason.

Maybe.... @lqd do you have any ideas?

[ChrisDenton]

Ok I've minimized it a bit more and realised that the crate-type in Cargo.toml seems to play a role. I need both "lib" and "cdylib" for this problem to occur.

[lib]
crate-type = ["lib", "cdylib"]

My minimization so far:

# Cargo.toml
[package]
name = "winit_test"
version = "0.1.0"
edition = "2021"

[[bin]]
name = "animation"
path = "src/main.rs"

[lib]
crate-type = ["lib", "cdylib"]

[profile.dev]
lto = "thin"

[dependencies]
winit = "0.28"

# .cargo/config.toml
[target.x86_64-pc-windows-msvc]
linker = "rust-lld

// src/main.rs
fn main() {
    winit_test::main();
}

// src/lib.rs
use winit::event_loop::{EventLoop, EventLoopBuilder};

pub fn main() {
    let _event_loop: EventLoop<u8> = EventLoopBuilder::with_user_event().build();
}

Doing cargo run results in:

error: process didn't exit successfully: `target\debug\animation.exe` (exit code: 0xc0000005, STATUS_ACCESS_VIOLATION)
