Description
In a freshly created bin, cargo build --release with the only dependency in Cargo.toml being nalgebra="0.24.1" gives a panic in rustc.
I am using rustc 1.65.0-nightly (060e47f 2022-08-23) running on x86_64-unknown-linux-gnu
I expected to see this happen: code compiles successfully
Instead, this happened: compiler panics with ICE:
cargo build --release
