One of the most important tools when writing unsafe rust is compiletest [1]. It's a tool extracted from the compiler project that lets you write tests that are supposed to fail compilation. Since safe abstractions rely on the type system to make unsafe code safe, it's critical to make sure the compiler is properly rejecting code. I wrote a post about this years ago when I got hit by one of the bugs Gankro wrote about [2].
