I’m always under the impression that C++ has some issues when it comes to embedded and that only a subset can be used, that the stdlib and stl cannot be used. I still don’t really understand how c++ behaves with exception handling thrown in the mix, where all sort of weird gotchas seemingly come into play.

I get templates, classes, and constexpr might be incredibly valuable though. If used within reason to avoid code size issues.

Has anyone spent serious time writing large firmwares in c++ with teams? What’s debugging like? How do people agree on what subset of the language and it’s plethora of features to use?
