fn f(_: usize, _: &usize, _: usize) {}

fn arg<T>() -> T { todo!() }

fn main() {
    let x = arg(); // `x` must be inferred
    // The reference on `&x` is important to reproduce the ICE
    f(&x, ""); //~ ERROR function takes 3 arguments but 2 arguments were supplied
}
Mitigate impact of subtle invalid call suggestion logic There's some subtle interaction between inferred expressions being passed as an argument to fn calls with fewer than expected arguments. To avoid the ICE, I'm changing indexing operations with `.get(idx)`, but the underlying logic still needs to be audited as it was written with the assumption that `final_arg_types` and `provided_args` have the right length.
