programming language design

Developers report that long-standing unsoundness bugs in Rust's borrow checker have been discovered after roughly 11 years, with details filed in the Rust compiler repository. The bugs allow memory-safety guarantees to be bypassed in certain cases, an ironic finding for a language designed around strong safety guarantees. Discussion centers on how such bugs survived so long and what fixes will be required.
