It isn't a violation of the standard. The Lakos Rule part where you
don't have a noexcept in the spec applies to narrow contracts,
the function will need to have Preconditions to have a narrow
contract, and calling it violating those Preconditions is UB.
The implementation can do anything, including throwing an exception.
