Backtrace
see above
This occurred in code different from the above but this is a minimal example that causes this failure. I believe I am disobeying some rules in the manner in which T is not bound in the underlying type of the trait. This bug appeared in my own code that worked with a previous nightly build. That code does bind T into the underlying type and still fails. If I bind it in this example with the following changes:
#![feature(generic_const_exprs)]
use std::mem::size_of;
trait X<T> {
fn f(self);
fn g(self);
}
struct Y<T>(T);
impl<T> X<T> for Y<T>
where [(); size_of::<T>()]: Sized {
fn f(self) {
self.g();
}
fn g(self) {
}
}the error goes away. I will need to create a minimal example that produces an ICE closer to the failure in my own code but I was struggling to do this. This is at least one ICE of interest and perhaps the unbound T should itself be prevented. I'm not entirely sure. Worthy of note, the following also compiles fine:
trait X<Word> {
fn f(self);
fn g(self);
}
struct Y;
impl<T> X<T> for Y {
fn f(self) {
<Y as X<T>>::g(self);
}
fn g(self) {
}
}which omits all of the generic_const_expr stuff.
