What to do depends on the environment you're running in. I've never used assert, so I had to look up the documentation, which says that it calls abort. Most application code won't catch an invalid_argument exception, so the effect will be similar.

In my open-source software, I neither throw nor assert in this situation. Instead, I generate a debug log with a traceback and return whatever signifies failure if the function has a result. That's appropriate if avoiding crashes is paramount, which is what my software aims for.

You're right that a reference shouldn't be null. For many functions, a pointer argument shouldn't be null either. But applications misbehave, so you have to decide whether your function will check for bad arguments or just crash.
