Code

// main.rs

type Value<'v> = &'v ();

trait Trait: Fn(Value) -> Value {}

impl<F: Fn(Value) -> Value> Trait for F {}

fn main() {
    let _: Box<dyn Trait> = Box::new(|v: Value| v);
}

using a rustc built from current master, with the following added to config.toml to enable overflow checks:

# config.toml

[rust]
overflow-checks = true
overflow-checks-std = false

Error output

rustc --edition=2021 main.rs -Csymbol-mangling-version=v0

thread 'rustc' panicked at compiler/rustc_symbol_mangling/src/v0.rs:298:22:
attempt to subtract with overflow


error: the compiler unexpectedly panicked. this is a bug.

note: compiler flags: -C symbol-mangling-version=v0

query stack during panic:
#0 [symbol_name] computing the symbol for `<alloc::boxed::Box<dyn Trait> as core::ops::drop::Drop>::drop`
#1 [collect_and_partition_mono_items] collect_and_partition_mono_items
end of query stack

This is the subtraction:

A smaller repro without involving core::ops::Fn or alloc::boxed::Box:

trait Fun<'v> {
    type Assoc;
}

trait Trait: for<'v> Fun<'v, Assoc = &'v ()> {}

fn main() {
    let _ = core::ptr::drop_in_place::<dyn Trait> as usize;
}

Oh that's only an artifact of the as cast in the minimal repro from #130011 (comment). 🙁 I need to try again with an actual drop.

Second attempt landed on #87784.

Third attempt (with env CARGO_PROFILE_RELEASE_OVERFLOW_CHECKS=true) landed on #83767. @camelid maybe you would be interested to take a look?
