Would Rust have prevented Heartbleed? Another look
Yeah but even Haskell (and I'm assuming Scala has something similar) has unsafePerformIO...

The Haskell 2010 standard includes Foreign.Ptr which allows direct, unsafe manipulation of memory:

As far as I understand, unsafePerformIO is not unsafe in relation to memory safety issues. It is just unsafe in that it circumvents the IO monad, which means order of execution is not guaranteed.

It's a different kind of unsafe, but my point is that it violates the normal guarantees of the language.

But there is a compiler flag -XSafe which could guarantee none of your code uses it, meaning GP's answer could be yes.

We have that switch in Rust as well.
