François, could you take a look please? The standard says:
> The insert and emplace members shall not affect the validity of iterators if
> (N+n) <= z * B, where N is the number of elements in the container prior to
> the insert operation, n is the number of elements inserted, B is the
> container’s bucket count, and z is the container’s maximum load factor.
The insertion does rehash, so should invalidate the iterators. It looks like
the _M_check_rehashed function only invalidates local iterators, despite the
order of elements changing.
