Chromium code replaces exceptions with boolean flags and logging or code to kill the current process for bad cases like out-of-bound access.
That's why we disable exceptions in video games.
For AAA / high-performance / console / close-to-the-metal video games, at least. There are tons of games where exceptions are perfectly fine. Though still more often used for "probably going to crash soon" situations than otherwise, I'd wager.
You can definitely do it but you’d be conceptually allowing for frame skips in your codebase. It could be difficult to audit and remove this assumption if down the road you wanted to tighten up your main loop code.
I am convinced that maintaining ABI is a huge technical debt to C++. And that is largely occasioned by shared libraries.
Rust IMO made a fantastic decision to emphasize source distribution (and making it super easy via cargo and crates).
If not exception, then how to fail constructor?
Consider this crap small code fragment. Any function that returns void is almost certainly wrong.
I don't use them. I just create an error type and pass that around.
The only legitimate exception I will accept is when you access invalid memory. That's a special case and depending on the environment something extraordinary must happen.
But exceptions and exception handling just creates annoying code. It doesn't add value, not really.

No.
We disable exceptions in video games for dumb historical reasons that no longer apply.

Why do we need to have ambient control flow? This is what exception handling is, it's a hidden control flow. I don't use them. I just create an error type and pass that around.
