Yes I know how static storage durations work. It's still global state, which is a code smell. Actually I'd go as far as to say global state is just bad practice, not just a smell. Occasionally it's the only option, and it's definitely the lazy option which I won't claim to never take!
Aaand.. you didn't even bother to google it :/
This is not about storage durations, and it's local to a function
I don't need to Google anything. I have 30 years experience writing C & C++.
Yes it is.

Only the visibility is local. The data is still global state. You can call that function from anywhere and it will use the same state. That's what global state means.

Some of the biggest issues with global state are that is makes testing difficult and it makes concurrent code more error-prone. Both of those are still true for locally scoped static variables.
