Compiler crashes on syntax error when trying to call a function from a dependency

[Larodar]

Hi,
I am running rustc 1.62.0-nightly (4c60a0e 2022-05-04) on x86_64-pc-windows-msvc
(via rust-toolchain.toml)

Code

I have a binary and a library. The binary depends on the library. The directory structure looks like this:

• somedirectory

  • binary

    • src
      • main.rs
    • Cargo.toml
    • rust-toolchain.toml

  • lib

    • src
      • lib.rs
    • Cargo.toml

The lib.rs has this one line.

pub fn get_root_dir() {}

The main.rs consumes this in the following way.

use lib::get_root_dir;

fn main() {
    test();
}

fn test() {
    let mut var = get_root_dir.to_owned();
    //                       ^ syntax error: It should be get_root_dir()
    var.push(""); // Deleting this line makes the compiler run just fine.
}

Error output

Setting RUST_BACKTRACE=1 did not make a difference.
I was not sure how to distinguish error output from the stacktrace. Thus, I left it in one piece.

thread 'rustc' panicked at 'DefId::expect_local: `DefId(16:3 ~ lib[2542]::get_root_dir)` isn't local', /rustc/4c60a0ea5b2385d7400df9db1ad04e96f2a4c154\compiler\rustc_span\src\def_id.rs:283:43

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

Errors without ICE on stable and beta:

error[E0599]: no method named `nonexistent_method` found for fn item `fn(_) -> Option<_> {Option::<_>::Some}` in the current scope
 --> src/main.rs:2:10
  |
2 |     Some.nonexistent_method();
  |          ^^^^^^^^^^^^^^^^^^ method not found in `fn(_) -> Option<_> {Option::<_>::Some}`
  |
  = note: `Some` is a function, perhaps you wish to call it

For more information about this error, try `rustc --explain E0599`.

This probably regressed in #92569, which added the expect_local which is panicking (DefId::expect_local should probably be #[track_caller]...)
