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 1.63.0-nightly (50b00252a 2022-06-06) running on x86_64-apple-darwin

note: compiler flags: --crate-type bin -C embed-bitcode=no -C split-debuginfo=unpacked -C debuginfo=2 -C incremental

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

query stack during panic:
#0 [typeck] type-checking `_::<impl at src/main.rs:54:17: 54:28>::deserialize::<impl at src/main.rs:54:17: 54:28>::visit_seq::<impl at src/main.rs:54:17: 54:28>::deserialize`

Possibly fixed by #97703

Triage: No one said it wasn't fixed, and that PR added regression tests. Let's close.
