"Illegal instruction" on 1.59

[rex-remind101]

I tried this code:

large private repo.

But altered our Dockerfile as such:
before:
FROM rust:1.57.0 as base
after:
FROM rust:1.59.0 as base
updating our rust version.

We use actix, and now cargo run --release results in the following soon after the web application starts:

Illegal instruction

If we run locally (not docker) using cargo run --release we get a similar error:

[1]    43322 illegal hardware instruction  cargo run --release

If we run locally not release cargo run we get the same error as above.

I expected to see this happen:
Virtually nothing changes, program operates as expected.

Instead, this happened:
Illegal instruction

Found this though seems smaller in blast radius #82278

I think I may have isolated the issue. There was a recent update in our panic handling. It's possible that that is panicing itself.

Yes, my mistake. This is an issue internally. My hope would be that Rust could provide a clearer error message, but will close.
