Abstract This project introduces Rustlantis, a novel fuzzer capable of generating programs in Rust’s Mid-level Intermediate Representation that are deterministic and free from Undefined Behaviour. It has uncovered 13 previously-unknown bugs in the Rust compiler and LLVM which has caused miscompilations as well as crashes.
These guys are so good at finding bugs that this article page gave me a “status code {null}”. Even when their stuff breaks there’s no error!
