Wat?
In which world are these compilers producing non-deterministic output if you run them again and again?

It's called reality that is also very trivially verified.

That's what I thought, too.

The one where deterministic iteration order (think use of unordered maps/sets, parallel execution, etc.) isn't considered a priority or is even seen as something to avoid as determinism here can lead to slower compiler times. Where there is use of heuristics that can have a "tie score" without effort to choose the winner deterministically. Where there is a need to support features like __DATE__ and __TIME__. So on and so on. It is a little out of the way so you've probably never heard of it, but its inhabitants call it "Earth".
