error: internal compiler error: compiler/rustc_passes/src/dead.rs:122:13: no type-dependent def for method #88643

Code

I'm too new to rust to know what part of this project is causing the compiler to crash, so I made a branch for it and removed the dependency on fltk. https://github.com/battjt/cb-test/blob/rustc_bug/src/main.rs

I just encountered a similar ICE with a slightly different source code (in the context of building a task planner). Here is the minimized code in playground:

trait Task<D> {}
struct Domain;
struct Collect;
impl Task<Domain> for Collect {}

fn main() {
    const POSSIBLE_TASKS: [dyn Task<_>] = [Collect];
}
