The "C is bad trope" is getting way too old. I'm surprised the author didn't plug Rust.
Maybe because it's one of the most widely used languages in the world...
The trope will be "old" once the mainstream view is no longer that C-style memory management is "good enough".
That said, this particular vulnerability was primarily due to how signals work, which I understand to be kind of unavoidably terrible in any language.
A better language wouldn't have any need to use POSIX signals in this way.
I'm not totally clear on why signals are used here in the first place. Arguably most C code doesn't "need" to use signals in complex ways, either.
