Description

There have been cases recently where clippy would crash if rustc was build with debug-assertions enabled.

https://github.com/rust-lang/rust-clippy/issues/3628
https://github.com/rust-lang/rust/issues/57298

To earlier catch regressions it might be helpful if we could get something like a rustc master tarball that has debug assertions enabled but I'm not sure if this exists.

Research direction

Start by reviewing the two linked Rust and Clippy issues, then inspect the repository's existing CI configuration. Determine whether a rustc master tarball with debug assertions is available and whether CI could use it. Done means a concrete, maintainable CI approach is identified and its coverage of debug-assertion regressions is clear.
