MIR panic during cross-chain queries #122083

Closed Twey closed 8 months ago

Twey commented 8 months ago

I ran into an ICE while building a large codebase in an invalid state with Rust 1.75.0.

Unfortunately I don't have time to make a minimal example right now, but I thought it might be worth putting the stack trace here anyway in case it's sufficiently informative!

Code

I've published the state of the code that triggered the ICE at https://github.com/Twey/linera-protocol/tree/03-06-ICE. I triggered it by simply running cargo build.

clubby789 commented 8 months ago

Can you reproduce this on stable Rust, or nightly?

Twey commented 8 months ago

This is stable Rust 1.75.0:

$ rustc --version --verbose
rustc 1.75.0 (82e1608df 2023-12-21)
binary: rustc
commit-hash: 82e1608dfa6e0b5569232559e3d385fea5a93112
commit-date: 2023-12-21
host: x86_64-unknown-linux-gnu
release: 1.75.0
LLVM version: 17.0.6

I can reproduce it from clean.

clubby789 commented 8 months ago

The current stable is 1.76.0

Twey commented 8 months ago

Oh, I can't keep up!

It doesn't reproduce on 1.76.0. Feel free to close if you like.

matthiaskrgr commented 8 months ago

Could be a duplicate of https://github.com/rust-lang/rust/issues/119786

jieyouxu commented 8 months ago

Closing as it seems to be fixed on stable 1.76.0.
