/// This won't work since doc tests are in a different crate
/// ```rust
/// const _:() = playground::test();
/// ```
pub const fn test() {
    let cl = const || {};
    cl();
}
const _: () = {
    // Works in this crate
    test();
};

playground link need to use test, since the error happens in the doc-test.

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 (afaf3e07a 2023-01-14) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type bin -C embed-bitcode=no -C debuginfo=2 -C incremental=[REDACTED]

note: some of the compiler flags provided by cargo are hidden

query stack during panic:
#0 [eval_to_allocation_raw] const-evaluating + checking `main::{constant#0}`
#1 [eval_to_allocation_raw] const-evaluating + checking `main::{constant#0}`
#2 [mir_drops_elaborated_and_const_checked] elaborating drops for `main`
#3 [optimized_mir] optimizing MIR for `main`
#4 [collect_and_partition_mono_items] collect_and_partition_mono_items
end of query stack
error: could not compile `consumer`

Anything else?

This occures if you call a function that uses const_closures from another crate.
