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:
end of query stack
error: aborting due to previous error

Anything else?

Only crashes on nightly and not beta or stable for some reason 🤔

Intresting, this is caused by cycle in function signature,
modify to below code will also get the error.

fn a() -> _ { &a }

and we have delayed errors like this:

error: internal compiler error[E0391]: cycle detected when computing function signature of `a`
 --> ./p/c.rs:1:1
  |
1 | fn a() -> _ { &a }
  | ^^^^^^^^^^^
  |
note: ...which requires type-checking `a`...
 --> ./p/c.rs:1:1
  |
1 | fn a() -> _ { &a }
  | ^^^^^^^^^^^
  = note: ...which again requires computing function signature of `a`, completing the cycle
note: cycle used when collecting item types in top-level module
 --> ./p/c.rs:1:1
  |
1 | / fn a() -> _ { &a }
2 | | fn main() { }
  | |_____________^
  = note: delayed at    0: <rustc_errors::HandlerInner>::emit_diagnostic
