// This is a separate test from `issue-66693.rs` because array lengths are evaluated
// in a separate stage before `const`s and `statics` and so the error below is hit and
// the compiler exits before generating errors for the others.
fn main() {
let _ = [0i32; panic!(2f32)];
//~^ ERROR: argument to `panic!()` in a const context must have type `&str`
// ensure that conforming panics are handled correctly
let _ = [false; panic!()];
//~^ ERROR: evaluation of constant value failed
// typechecking halts before getting to this one
let _ = ['a', panic!("panic in array len")];
