`catch_unwind` broken on `armv7-apple-ios` #156

Closed madsmtm closed 1 year ago

madsmtm commented 2 years ago

Tried the following on my iPad (1st generation, iOS 9.3.6), not sure if this is a Dinghy error or a rustc error?

// main.rs
fn main() {
    let res = std::panic::catch_unwind(|| {
        panic!("test");
    });
    println!("{:?}", res);
}
# Cargo.toml
[package]
name = "ios-panic"
version = "0.1.0"
edition = "2021"

[[bin]]
name = "ios-panic"
path = "main.rs"
# .cargo/config.toml
[unstable]
# To allow building for armv7-apple-ios
build-std = ["core", "alloc", "std"]

Run with RUST_LOG=dinghy=debug cargo +nightly dinghy --device ipad run.

This is indeed a rustc error, will be fixed by https://github.com/rust-lang/rust/pull/99932
