Description
Another self_struct_ctor internal compiler error very similar to #56202
A minimal example:
#![feature(self_struct_ctor)]
trait FooTrait {}
trait BarTrait {
fn foo<T: FooTrait>(_: T) -> Self;
}
struct FooStruct {
x: u32,
y: u32,
}
impl BarTrait for FooStruct {
fn foo<T: FooTrait>(_: T) -> Self {
Self(0)
}
}error: internal compiler error: src/librustc/hir/def.rs:267: attempted .def_id() on invalid def: SelfCtor(DefId(0/0:1103 ~ rng_av[108c]::parameters[0]::{{impl}}[8]))
