Steps to reproduce: 1. Ensure the test env has 2.36-9+deb12u6 2. Install the latest rust toolchain. 3. mkdir test_test && cargo init 4. ensure src/main.rs has ``` fn main() { println!("Hello, world!"); } #[test] fn test() { println!("hAAA!"); } ``` 5. create .cargo/config.toml ``` [target.aarch64-unknown-linux-gnu] linker = "aarch64-linux-gnu-gcc" runner = "qemu-aarch64 -L /usr/aarch64-linux-gnu" rustflags = ["-C", "target-cpu=neoverse-n1"] ``` 6. cargo test --target aarch64-unknown-linux-gnu Additional information: The issue does not seem to occur with libc6:2.36-9+deb12u4 The same binary runs fine on a real arm64 target with the upgraded libc6 version 2.36-9+deb12u6.
