error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.69.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: -Z codegen-backend=cranelift

Hmm something is messed up with collections..?
This also crashes crashes cranelift:

const V: Vec<i32> = Vec::new();

pub fn main() {}

[matthiaskrgr]

ah nevermind, an empty main also makes it crash? 😆 pub fn main() {}

[bjorn3]

This should have been fixed by bjorn3@8494882, but that commit is not yet synced back to the rust repo.

[matthiaskrgr]

Hm, when is the next sync? 😅 because right now it seems cranelift is monstly unusable built from the rustc repo like that... 😕

[bjorn3]

I can probably do a sync tomorrow.

merged.
