error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.68.0-nightly (333ee6c46 2023-01-18) running on x86_64-unknown-linux-gnu

query stack during panic:
#0 [typeck] type-checking `main`
#1 [typeck_item_bodies] type-checking all item bodies
#2 [analysis] running analysis passes on this crate
end of query stack
error: aborting due to 2 previous errors

For more information about this error, try `rustc --explain E0658`.

Anything else?

No response

[clubby789]

Seems to have regressed in #106822, #106585 looks relevant

[justinpombrio]

I ran into this as well. My minimized version, in case it's helpful:

fn main() {
    let mut result = vec![(1, 'a')];
    let mut vector = Vec::new();
    vector.sort();
    result.push(vector);
}

(Same index out of bounds error in snapshot_vec.rs, same rustc version.)

[compiler-errors]

@justinpombrio this is actually a different ICE. Can you file a different issue for this?
