Description
What I expected to happen
A completely valid and fine Diesel 1.4 table definition, as it compiles just fine on any version:
use super::schema::messages;
use chrono::{DateTime, Utc};
#[derive(Queryable, Insertable)]
#[table_name = "messages"]
pub struct Message {
}where schema can be anything. There can be any fields in the struct as well.
What actually happened
A proc-macro panicked for use-after-free: macro-error: proc macro returned error: proc-macro panicked: use-after-free in `proc_macro` handle.
Note that this only affects the derive macros; every other warning and whatnot still shows up, such as an unused lifetime on the struct if you define it to have <'a>.
Regression
This is only broken on cargo 1.54.0-nightly (2021-05-11). When tested on cargo 1.52.0 (69767412a 2021-04-21) and cargo 1.53.0-beta (4369396ce 2021-04-27), all is well. cargo build and cargo check both work as expected on all environments.
