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 1.59.0-nightly (cfa3fe5af 2021-12-31) running on x86_64-apple-darwin

note: compiler flags: -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 [codegen_fulfill_obligation] checking if `serde::de::Expected` fulfills its obligations
#1 [resolve_instance] resolving instance `<dcx_types::resource::metadata::_::<impl serde::de::Deserialize<'de> for dcx_types::resource::metadata::RepoMetadataResource>::deserialize::__Visitor as serde::de::Expected>::fmt`
#2 [vtable_entries] finding all vtable entries for trait serde::de::Expected
#3 [collect_and_partition_mono_items] collect_and_partition_mono_items

I'm also affected, I get this panic frequently (every 4-5 incremental builds).
Here's the backtrace I get just in case:

Also got this same error. I haven't been able to reproduce it since it happens only with occasional incremental builds. These are the Adlist and AdlistFormat mentioned in the backtrace (the serde feature is enabled):

use url::Url;

#[derive(Debug)]
#[cfg_attr(feature = "serde", derive(serde::Deserialize, serde::Serialize))]
pub struct Adlist {
    pub(crate) source: Url,
    #[cfg_attr(feature = "serde", serde(default))]
    pub(crate) format: AdlistFormat,
}

#[derive(Debug, Clone, Copy)]
#[cfg_attr(
    feature = "serde",
    derive(serde::Deserialize, serde::Serialize),
    serde(rename_all = "lowercase")
)]
pub enum AdlistFormat {
    Hosts,
    Domains,
    DnsMasq,
}
