> You can even get double free in Rust if you take the time to build an entire machine emulator and then run something that uses Malloc in the ensuing VM. Rust and similar memory safe languages can emulate literally any problem C can make a mine field out of..
That doesn't have any relevance to a discussion about memory safety in C vs rust. Invalid memory access in the emulated machine won't be able to access memory from other processes on the host system. Two languages being turing complete does not make them the same language. And it definitely does not make them bug for bug compatible. Rust _really_ does enable you to write memory safe programs.
Invalid memory access in C also won't be able to access memory from other processes (on a modern computer, outside the OS).
Sounds like you actually agree with the comment you are replying to.
