This appears to be a different way to reproduce #114212
@rustbot label +F-generic-const-exprs +requires-incomplete-features
Thank you for bringing this🤗. Upon a thorough review, it appears that the query stacks for these two issues differ, suggesting that they are distinct Internal Compiler Errors (ICEs). However, we also notice that the compiler versions associated with these issues also differ. Thus, we cannot ascertain whether the variance in the query stack is because of the compiler versions.
These seem like related but different issues, or maybe the same issue but changed in newer compiler versions. Edit: same issue, the file was renamed in #113591
I encountered an ICE similar to this one, but with a pattern more similar to the older issue:
pub const SIZE: usize = 8192;
pub struct Segment<
const N: usize = SIZE, // replacing with literal 8192 fixes it
T = u8
> {
_data: PhantomData<T>
}
The source of the panic is generic_args.rs:900:9
, whereas in the linked issue it's subst.rs:896:9
. I'm on the latest nightly, 1.74.0 (2023-08-26).
Here's my backtrace, if it's helpful:

Thank you very much for your reply. I think I have gained a better understanding of Rustc😃🚀
@rustbot claim
Duplicate of #106994
Perhaps we can close this one in favour of that.
