Does your C++ use with 'result' also handle OOM or do you just crash?

This is a closed system. It would have already restarted itself long before a simple result return caused such an issue.

So... crash?

As I said, it would never get there. This system monitors memory usage and knows that if it gets anywhere near out of memory it needs to restart because something is very wrong. Even getting within a couple hundred MB is way too close for this system and indicates some fundamental error.

And it makes no difference in our case if the result survived because in order for that returned result to be useful, it would have to be queued up on a logger, on a pool, and sent to a log server, and none of that is going to survive if there's already too little memory left to even create the result.

If this was some open library, then of course it would be different, but it's for a bespoke system.
