auto-reduced (treereduce-rust):

fn main() {
    let _ = <Foo as A>::Assoc { br: 2 };

    let <E>::V(..) = E::V(|a, b| a.cmp(b));
}

struct StructStruct {
    br: i8,
}

struct Foo;

trait A {
    type Assoc;
}

impl A for Foo {
    type Assoc = StructStruct;
}

enum E {
    V(u8),
}

    // destructure through a qualified path

It appears I'm hitting this one as well. Tacking this on for good measure.

Looks like it was originally introduced here in this commit by @lcnr (and was renamed later to own_args without any change in functionality).

I'd PR a fix but I'm not entirely sure how it's supposed to work. Is this masking a deeper bug or can one simply do something like:

-let own = &substs[self.parent_count..][..self.params.len()];
+let own = &substs[self.parent_count..];
+let own = &own[..self.params.len().min(own.len())];

Derp, missed there was a PR. #128337 indeed fixes this on my end. Thanks @bvanjoi for the quick fix on this!

Rollup merge of rust-lang#128337 - bvanjoi:issue-121613, r=compiler-errors skip assoc type during infer source visitor Fixes rust-lang#121613 Due to the generic arguments being lost during normalization, the associated type cannot retrieve the correct generics information, so this PR follows this [comment](https://github.com/rust-lang/rust/blob/master/compiler/rustc_trait_selection/src/error_reporting/infer/need_type_info.rs#L937-L942) and skips `DefKind::AssocTy` r? `@lcnr`
