Just because emotions seem to be always boiling whenever Rust is mentioned, I want to clarify for people who only follow casually that there is nothing unusual or scandalous about these finds.
The Rust project as a whole currently has 178 open issues with the tag I-unsound[1]. Many of these describe issues that only exist in the nightly compiler, of course, but it does happen that bugs are not caught before shipping. That's software.
