@ecstatic-morse, it looks like this match needs to be updated somehow:
Does this bug report contain enough information to understand the problem, or do you need an MCVE?

Could you reproduce but debug print the the scrutinee in the bug arm?

I'm surprised since we should return before calling mir_const_qualif for all other types. https://github.com/rust-lang/rust/blob/d20113d0f590858c8fea34ebcb1c54c93ae79714/src/librustc_mir_build/hair/pattern/mod.rs#L768-L773
It must be one of the AssocContainer::Trait* variants. That means we're using the DefId of the associated const definition instead of the declaration. Maybe a defaulted associated const? I dunno.

Indeed, here's the source for the item being checked (specifically, NAME):
pub trait ServiceMarker: Sized + Send + Sync + 'static {
/// The type of the structure against which FIDL requests are made.
/// Queries made against the proxy are sent to the paired `ServerEnd`.
type Proxy: Proxy<Service = Self>;
/// The type of the stream of requests coming into a server.
type RequestStream: RequestStream<Service = Self>;
/// The name of the service suitable for debug purposes.
///
/// This will be removed-- users should switch to either
/// `DEBUG_NAME` or `DiscoverableService::NAME`.
const NAME: &'static str = Self::DEBUG_NAME;
/// The name of the service suitable for debug purposes.
///
/// For discoverable services, this should be identical to
/// `<Self as DiscoverableService>::NAME`.
const DEBUG_NAME: &'static str;
}
Ah okay. We should already be encoding the ConstQualifs for associated type defaults. If so, just adding an | AssocContainer::TraitDefault would resolve the issue. I think I can synthesize a test case from here though, so don't worry about reducing further. Thanks for the help!

No problem! Since I'd kicked this off already, here's the debug print:
AssocConst(TraitWithDefault, ConstQualifs { has_mut_interior: false, needs_drop: false, custom_eq: false }, Lazy { position: 222765, meta: (), _marker: PhantomData }
