🚨Rust Soundness Bug Affects Programs Since 1.4
Rust's soundness hole could break your code
TL;DR
A critical soundness hole in Rust since 1.4 can cause programs to compile and run incorrectly, potentially crashing or leaking memory. The types team is reviewing the issue.
A critical soundness hole in Rust since version 1.4 can cause programs to compile and run incorrectly, potentially crashing or leaking memory. This bug, related to the borrow checker and destructors, can bypass covariant field assignment and affect the lifetime requirements of structs. If you're using Rust in production, this is a big deal. The bug can cause programs to crash with AddressSanitizer errors or print freed memory. The types team is reviewing the issue, which is high-priority and affects all Rust versions since 1.4.
Key Points
