Code

#![feature(adt_const_params)]
#![allow(unused_must_use, incomplete_features)]

pub const BAR: () = ice::<"">();
pub const fn ice<const N: &'static str>() {
    &10;
}

fn main() {}

Meta

ICE only occurs with debug assertions so the version is just "latest commit on master"

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 1.57.0-dev running on x86_64-unknown-linux-gnu

query stack during panic:
#0 [mir_for_ctfe] caching mir of `ice` for CTFE
#1 [eval_to_allocation_raw] const-evaluating + checking `BAR`
#2 [eval_to_const_value_raw] simplifying constant for the type system `BAR`
#3 [eval_to_const_value_raw] simplifying constant for the type system `BAR`
#4 [analysis] running analysis passes on this crate
end of query stack
