Rust is one such language. I wrote a bit about exception safety in Rust here: https://users.rust-lang.org/t/c-pitfalls-hard-to-avoid-that-... In short, while the problem is mitigated somewhat compared to C++, it's still one of the most common causes of bugs in unsafe Rust code. Rust programs can choose to abort on all panics, rather than unwind. Firefox does this, for example. |

While we can benefit from #[no_std] crates on crates.io, unfortunately we can't use any crates that require standard because the standard library does not propagate errors properly, so we maintain our own implementation of most of the standard library for Linux only, that propagates all errors using Result..
It's a huge pain point, but at least Rust allows us to do it.
