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 1.65.0-nightly (1120c5e01 2022-09-08) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib -C opt-level=3 -C embed-bitcode=no -C debuginfo=2 -Z unstable-options -C force-frame-pointers=yes

error: could not compile `once_cell`
warning: build failed, waiting for other jobs to finish...

[jannic]

To reproduce this, try to build once_cell for an architecture which doesn't have std. Eg:

once_cell$ cargo +nightly build --target thumbv6m-none-eabi
   Compiling once_cell v1.14.0 (/home/jan/tmp/once_cell)
thread 'rustc' panicked at 'identifier: "metadata_std_required", attr: None, args: FluentArgs([("add_info", String("")), ("crate_name", String("std")), ("locator_triple", String("thumbv6m-none-eabi"))]), errors: [ResolverError(Reference(Variable { id: "current_crate" }))]', compiler/rustc_errors/src/translation.rs:91:17

This was with version 1.65.0-nightly (646e9a0b9 2022-09-02).

For comparison, with stable rust 1.63.0, the error is:

$ cargo +stable build --target thumbv6m-none-eabi
   Compiling once_cell v1.14.0 (/home/jan/tmp/once_cell)
error[E0463]: can't find crate for `std`

  = note: the `thumbv6m-none-eabi` target may not support the standard library
  = note: `std` is required by `once_cell` because it does not declare `#![no_std]`
