If you throw a bad_alloc, you don't need to add a full fledged error message, I agree that the localization and the exception type is sufficient.
When you throw a logic_error, more the message is clear, precise and detailed better it is.

I agree for bad_alloc exception, but as before you don't really need a message in this particular case.
If you throw a logic_error, you don't have more chance to encounter a bad_alloc than everywhere in your application.
